5. OPERATION
5.1. WARNINGS
Different warnings or information can be reported during manipulation with the APPLIANCE MULTITESTER. Here is a list of
warnings and information for each function.
HV AND PROG.HV FUNCTION:
Trip out
The HV generator tripped-out due to the test current, which was higher than the set threshold
value.
CONTINUITY FUNCTION:
Load on TEST SOCKET
External AC voltage connected to CONTINUITY
or
input C1 – C2 (voltage present on P1 and P2 too), or
Voltage on term. C1-C2
TEST SOCKET loaded.
Voltage on term. P1-P2
External AC voltage connected to CONTINUITY input P1 – P2 is higher than 12 V (voltage
present on C1 and C2 too).
VOLTAGE DROP FUNCTION:
Load on TEST SOCKET
External AC voltage connected to CONTINUITY
or
input C1 – C2, (voltage present on P1 and P2 too) or
Voltage on term. C1-C2
TEST SOCKET loaded.
Voltage on term. P1-P2
External AC voltage connected to CONTINUITY input P1 – P2 is higher than 12 V (voltage
present on C1 and C2 too).
ISO FUNCTION:
Voltage on term. ISO
External AC or DC voltage connected to ISO terminals is higher than 30 V.
DISCHARGING TIME FUNCTION:
Ready
displayed for approx. 1 s after pressing START.
Low Voltage
displayed if the voltage on input mains is not appropriate or not connected.
Start
displayed if disconnection voltage is high enough to carry out measurement, and the
measurement will be performed.
Repeat
repeat measurement.
Time out
displayed if the connection element is not pulled out in 10 s or discharging time is higher then
10 s.
GENERAL:
HOT
The instrument is overheated (CONTINUITY, VOLT.DROP, HV and PROG.HV);
sign is
also displayed.
Fig. 47. Example of hot message
Measurements in functions ISO, LEAK.CURRENT, FUNCTION. TEST and DISC.TIME can still be carried out.
No Earth
Earth connection is missing on mains power plug.
No Voltage on TEST SOCKET
Check Fuses F3, F4 (16 A T).
Load on TEST SOCKET
Test socket is loaded in functions other then Leakage, Disch. time and Functionality.
Voltage on term. P1 - P2
Ext. AC voltage connected to P1-P2 input is higher than 12 V (voltage present on C1
and C2 too).
Voltage on term. ISO
External AC or DC voltage connected to ISO terminals is higher than 30V.
