Maintenance
This section gives procedures to maintain the unit in a good
condition. Return the instrument to the supplier for all repairs.
Maintenance – Clean the unit
Clean the case with a moist, lint-free cloth and a weak detergent.
Do not use solvents or abrasive materials.
Maintenance – Replace the batteries
To replace the batteries, refer to B1. Then re-attach the cover.
Make sure that the time and date are correct. The calibration
facility uses the date to give service and calibration messages.
All the other configuration options stay in memory.
Maintenance – Recalibrate the unit
Note: GE Druck can provide a calibration service that is
traceable to international standards.
Before you start the calibration, make sure that the time and date
are correct (Table1).
To get accurate results, do the calibration in stable temperature
conditions, and to the applicable calibration standards.

When you select a channel, the display shows the applicable
instructions to complete the calibration.
Table 5: .Calibration options
When the calibration is complete, select Calibration Due and set
the new calibration date.
Calibration: Measure mV
The specified accuracy (refer to “Specification”) includes an
allowance for temperature changes, reading stability for one
year, and the uncertainty of the standard used for calibration.
GE Druck recommend that you return the instrument to the
manufacturer or an approved service agent for calibration.
If you use an alternative calibration facility, make sure that it
uses these standards:
• Accuracy of the mV calibration equipment:
0.008%reading + 0.003% FS or better.
• Calibration limit for the instrument (mV measure): 0.01%
reading + 4 µV or better.
Step Procedure
➀, ➁A1 - Item [9a] (Optional): Connect the 5-pin connector to the IDOS instrument.
➂A1 - Item [9a] (Optional): Connect the 9-pin connector
to the serial port on the PC or to a serial printer (refer
to the PC or printer instructions).
➃PC: Make sure that Windows® HyperTerminal or
similar program is set up to use the specified data
format (refer to your PC on-line Help).
Serial printer: Make sure that the printer can use the
specified data format.
Data format
Baud rate: 19200
Parity: None Data bits: 8
Stop bits: 1

➄Transmit the data to the PC or printer (Table4).
PC: Use Windows® HyperTerminal or a similar
program to make a text file. You can then import the
text file into a spreadsheet.
