11.10 Loop 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.
“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 Earth test
“Err REv” - During a 2-clamp test, one clamp is the wrong way round.
“Err” + V clamp symbol -During a 2-clamp test, the V clamp has been opened.
“Err” + I clamp symbol -During an ART test, the I clamp is the wrong way round.
“Err” + Rp symbol -Rp resistance is too high.
“Err” + Rc symbol -Rc resistance is too high.
11.12 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
“FRE >65” -Supply frequency is too high for loop test or rcd test
“NO REF” -Loop R1+R2 test attempted without having previously done a Zref test.
