2. Description of Special Symbols
(1).
Symbol of an open jaw: As a jaw is in the open state, the symbol
shows. At this point, trigger may be artificially pressed, or the jaws have been
seriously polluted, and can no longer continue to measure.
(2).
Symbol of low battery voltage: when the battery voltage is lower
than 5.3V, the symbol shows. At this time, it cannot guarantee accuracy of the
measurements. Batteries should be replaced.
(3).
"
OL Ω
" symbol indicates that the measured resistance has exceeded
the upper limit of the Meter.
(4).
"
L0.01Ω
" symbol indicates that the measured resistance has
exceeded the lower limit of the Meter.
*(5).
"
OL A
" symbol indicates that the measured current has exceeded the
upper limit of the Meter.
*(6).
Alarm symbol: when the measured value is greater than the
critical value of alarm setting, the symbol flashes.
*(7).
Symbol of full data storage: memory is full of data units of 50,
and can no longer continue to store data.
*(8).
Symbol of access to data: to display in an access to data, also
including the number of data.
*(9).
Noise signal: the symbol shows in the measurement of
grounding resistance at a greater interference current in the loop. At this time it
cannot guarantee accuracy of the measurements.
Note: "*" is limited to ETCR2000C.
