“bAt” -Low battery
11.3 Battery charger
“bAt CHA” -Battery charging
“bAt FUL” -Battery fully charged
11.4 Fuse warning
“FUS” -Fuse blown.
11.5 Invalid rotary switch setting
“ERR - - -“ -General error – invalid combination of rotary switches.
11.6 Continuity test
“VOL 0-L” -Voltage overload during test
11.7 Insulation test
“1000 V 1000 V” -Flashing warning before 1 kV test.
“VOL 0-L” -Voltage overload during test
11.8 RCD Test
“trp” -Supply tripped unexpectedly.
“>50V” -Test aborted due to danger of exceeding touch-voltage limit.
“Err con” -Hardware problem detected during High Current Loop test or RCD test.
11.9 RCD range selection errors
“ERR >1000 mA” -Requested current is >1000 mA.
“ERR - - -“ + Type A -In Type A mode -Instrument has been set for Type A test, but Type A test is not valid
with this setting.
“ERR - - -“ + Type B -In type B mode - Instrument has been set for Type B test, but Type B test is not valid
with this setting.
“ERR - - -“ + Type S
breaker symbol -Instrument has been set for Type S test, but Type S test is not valid with this setting.
“ERR HI mA” -On VAR range, current is set too high for the selected test.
11.10 Loop Test

“>50V” -Test aborted due to danger of exceeding touch-voltage limit.
“Err con” -Hardware problem detected during High Current Loop test or RCD test.
“hot” -Internal resistors are too hot. Also shows thermometer.
“Hot” -Internal heat sink is too hot. Also shows thermometer.
-Supply noise detected. Loop test time will be extended.
11.11 Test will not start
“CON” -Wrong connection to instrument.
“hot” -Internal resistors are too hot. Also shows thermometer.
“Hot” -Internal heat sink is too hot. Also shows thermometer.
“VOL >280V” (for example) -Supply voltage is too high.
“L-N <48V” (for example) -Voltage on terminals is too low for L-N loop test
“L-E <48V” (for example) -Voltage on terminals is too low for L-E loop test or rcd test
“FRE <45” -Supply frequency is too low for loop test or rcd test
