As a default the display background lighting remains lit for 1 minute after a key is pressed. The lighting can be switched off permanently or a custom illumination period can be set. Changes in menu 1.4.1

Under menu item 4., there is a commissioning procedure for MIQ, MIL, MLT and MPR units. In this procedure, all relevant parameters are chronologically queried during initial commissioning.
The parameters for the MLS and MAT are entered individually into the corresponding menu items.

Measurement value too low: mA output drops to the value programmed in menu item 8.3! Relays drop. Potential cause: Broken cable, alteres on-site electronics MTI
Measurement value too high: mA output drops to the value programmed in menu item 8.3! Relays drop. Potential cause: Measurement value is higher than 3750 impulses, altered on-site electronics MTI

All mipromex® microprocessor devices are equipped with a diagnostic system that makes troubleshooting easier and helps resolve errors faster.

Technical error incidents at mipromex® that require the device to be sent to aquasant® for repair:

• Flash storage checksum review failed
• Flash saving process failed
• Low battery: Battery is discharged and has to be replaced
• Program memory check failed

The interface layer measurement is designed for fluid/fluid phase separation.

The MIQ model can be parameterised for continuous batch separation with for STM bar probes or TSS80 tube probes. The low-cost alternative is the MIL device for continuous interface monitoring.

For continuous measurement, the measurement values for both phases must be determined during commissioning and saved in the measurement device.
Batch separation does not require commissioning. The 100% point for aqueous layers is already saved in the system. It is a plug&process system. On delivery, the MIQ8130 evaluation unit is parameterised for dynamic detection.

The measurement range (menu 3.1.5) for the calculation of the 100% measurement range is product-specific. This measured impulse value is determined by the product by covering the entire active measuring electrode and saving the displayed impulse value by pressing a key. (The default setting is done with water, electrical conductive)

In the home position (menu 1.1), the languages: German, English and French can be selected.
Select the desired language to be indicated on the display. After selecting and saving the language, it will be activated immediately.

The password protection limits the user’s access to the programming level of mipromex®. The first time the system is switched on, the password is set to 0000 as a default and is displayed. If this password is changed under item 1.3, every user must log in with the new code! Note: If the new password is lost, contact aquasant® so we can provide you a master password.

If the password is not confirmed, the data can be seen in the menu, but not modified.

The probe factor is a probe-specific coefficient that specifies the ratio to the probe standard (factor 1.00). If you replace the probes, you still have a reproducible measurement with the same measurement values. This only has to be done for a replacement probe so the same number of impulses is reached at 100%. (3.1.2.)

During continuous interface monitoring, 50 different product measurement values can be stored with the product name. 7 different combinations can be defined and saved. The phase combinations for multi-purpose plants can be queried and selected from the PCS via the digital inputs.

There is a first order signal filter. You can dampen the raw measuring signal using the freely selectable filter time constant (max. 30 seconds). Display value and current output are averaged. (Menu 3.1.16).

The probe has a base capacity. It is compared to the MTI integrated electronics and can be saved as a zero point in the mipromex® evaluation unit. The zero point comparison of the probe is saved under menu item 3.1.3.

If the measurement value is too high and the “OVL” (overload) is on the display, the amplification can be reduced manually. The zero point is also adjusted during this adjustment under menu item “2.2.7 Amplification”. That means it is not necessary to recalibrate the zero point. When manually recalibrating, the end and zero points also have to be calibrated. The end value and the scale value are also automatically recalculated after the amplification is adjusted. Another amplification can be selected at any time.

The generated calibration data is saved under the saved serial numbers which can be loaded or deleted. Simply select the desired calibration file and press the “Enter” key.
Attention: Max. 5 calibration files can be generated. If there are already five calibration files when a recalibration is performed, at least one of them must first be deleted. If there are no calibration files when switching on the unit, the unit will indicate that no calibration files have been loaded by displaying “no” on the screen.

Notification:
• Communication error with preamplifier: Red LED is blinking, current output at 2 mA
• Memory full, contact aquasant®
• OVL measurement value too high: Recalibration required

If you did not perform a linearisation process during the automatic calibration, it can entered later under menu item “2.2.10 Linearisation”. To do this, the probe must be immersed in the lowest reference solution. Using the “+” and “-” keys, select the desired linearisation point. A maximum of six calibration points can be entered.

Basis of the reflection
The infra-red radiation,emitted by a controlled IR transmitter (880m) and coupled into the fibre-optic transmission line is emitted into the medium from two sides of the probe. The back-scattered IR is transmitted to the measurement electronics via the fibre-optic receiving line with high-precision receiving optics.

The default password is 1234 and can be changed. If the password is lost, this setting can be deleted. The 2 and 4 keys have to pressed simultaneously for three seconds until the delete menu appears. After the password is deleted, the device will adopt the default password. You can exit the menu by pressing “Back” without deleting the password.

If a turbidity sensor is replaced, it has to be recommissioned.

The following steps must be followed for calibration:
a) Enter the probe’s serial number under “Menu item 2.2.2”.
b) Perform the automatic calibration
c) Adjust the integration time if necessary.
d) Select new measurement if you do not want to measure “online”.

The unit can be freely selected under menu item “2.2.9 Unit”.
The turbidity standard Formazin or Amco is specified in NTU:
• FNU (Formazine Nephelometric Units)
• FTU (Formazine Turbidity Unit)
• NTU (Nephelometric Turbidity Unit)

The measuring process and the important parameters of the ATM100 can be downloaded, converted and edited via the Ethernet port. The txt file contains important header information and the measurement values with the corresponding time stamp. These files can be edited directly in Excel for further processing.

The ATM100 turbidity measurement device can be configured via Ethernet using Internet Explorer or another web browser. For network settings, see explanations under menu item “4. Network” in the operating instructions.

The fluorescence spectral photometer can be equipped with four LEDs in the range of 310-1025 nm.

ATFM200 Suite is the PC user interface for the spectromex® electro-optical fluorescence spectral photometer. The ATFM200 Software Suite can be used to calibrate, configure and control the spectromex®.

If the probe is compared using a potentiometer, the LEDs light up. If both LEDs are blinking, this means the measurement value is around 63 impulses which will be saved as the zero point in the evaluation unit.

2 What does the value MTI ../0,../1, mean?

This value specifies the sensitivity. For example: An MTI 50 is five times less sensitive than a corresponding MTI 10. The determined measurement value with a defined probe of 650 impulses thus results in 3250 impulses with an MTI 10.

Only with limits because the Cabalec and casting compound are not suitable for all solvents. Preferably, the stainless steel version of the sensor, the AF23R, should be used.

It is possible, but only with the corresponding AS9 control unit and the VE9 on-site electronics.

NO, the explosion protection is only guaranteed using the respective, corresponding AF sensors. The sensor electronics of the electro-optics is designed in combination with the AS control unit.

There is a zero potential switch contact for each channel.

No, but they have been tried and tested on the market for 45 years.

The AF33R; this overflow protection guides the fibre-optic line into the tank and to the optics. The coupler electronics are housed in the connection head.
