• Check date and time.
• Check whether the mL-code does correspond with the exchange unit placed or not.
For the sake of completeness, different exchange units can be inserted to check their mL code. If desired, the ex-
change unit can be removed again. If no exchange unit is inserted display does not show the mL-code but „check
exchange unit !“.

5 Analogue output test
A voltage can be set at the analog output (sockets at D) using the kexpad. But this should not exceed ± 2000 mV. This volt-
age can also be used for the calibration of a connected recorder.
• Connect a voltage measuring instrument (voltmeter, DVM, recorder) to the ana-
logue output (10).
• Press <3>.

• Press <Enter>.
analog output-1 test
V-out = XXmV
Enter a voltage value in the range
± 2000 mV using the keypad. After the <ENTER> key has
been pressed, this value appears as a voltage at the analog output..
Read off value an the connected voltmeter and compare with the mV value on the display.
