7 How to Work With the Analyser
7.3 Good to know LAR | PROCESS ANALYSERS AG
Only an authorized technician should perform an analog output calibration, as this requires opening the
rear housing.
1. Open the rear part of the unit.
2. Connect the multimeter (amperemeter) to the analogue output.
3. In the Calibrate Analog Output view, specify the number (analog output) to which the multimeter is
connected.
4. Click on the desired mA value (0, 4, 10, 12 or 20 mA).
5. The mA value must be recognizable on the ammeter. If a different value is displayed, please
contact LAR technical support (Chapter 15.1 on page 183).
6. After checking the analog output, close the rear part of the unit.

7.3.1 Password
The password can be changed to user level 2 (PC Settings screen). When changing the password, this
should be documented in a safe place. If the default password has been changed or deactivated, a USB
stick with access level 2 access rights becomes necessary. The USB stick is delivered in a separate
spare parts container.
7.3.2 Software Version
The opening screen (Fig. 52, page 88) and the PC Settings screen (Fig. 86, page 122) show the
current software version number.
7.3.3 Abort Measurement
The measurement continues until it is canceled by pressing the "Offline" button (top right). The device is
then put into the wait state and all measurement data not yet stored are stored. Now you can carry out
maintenance work (Chapter 7.2.12.2 on page 108), evaluate old measuring data or change operating
parameters (measuring frequency, etc.). If the measurement was e.g. interrupted by a power failure, an
autostart will be performed when the power is restored and automatically returns to the measurement
mode. The unit continues its programmed measurement cycle after the power failure without operator
intervention.
Notice
Before checking all possibly already connected signal cables for
Remove process control system (connections to analog outputs).
Notice
The default password is given by LAR AG at the factory and reads: lar
For security reasons, a USB stick with access level 2 access is required if the pass-
word is disabled or changed.
