4.0 Testing

4.1 Preparations and Safety Measures
Insert battery:
Insert battery, prior to commissioning. Proceed as
follows:
1. Disconnect the instrument from measurement
circuit.
2. Open the casing by pulling the rear casing cover
towards the bottom.
3. Insert new batteries, type 1.5 V IEC LR6 by re-
specting the polarity and close the casing again.
4. Connect test leads in switch position
The beep must be clearly audible (UNITEST
TESTFIX electronic, additional green lighting of
DOUBLE LED).
5. Connect test leads in switch position
The lamp must be cleary visible (UNITEST TEST-
FIX electronic, additional green lighting of
DOUBLE LED).
Only use continuity tester, if all display elements
function perfectly.
6. Now you may start testing.
Remark:
If lamp does not work or is missing, no conitnuity
test can be performed!
Ensure that UUT is voltage-free. Verify this con-
dition, if required, by using e.g. UNITEST Digital
Multimeter 93427.
• Only use the instruments in dry and clean environ-
ments.
• Prior to any usage, verify perfect instrument ope-
ration.
• Verify perfect condition of test leads.
4.2 Continuity and Line Testing
Continuity testing has to be carried out when sy-
stem parts are voltage-free. If required, dischar-
ge capacitors. Prior to testing, verify that the cir-
cuit is voltage-free by using an appropriate
measurement instrument, e.g. UNITEST Digital
Multimeter 93427.
