symbol shows. At this point, trigger may be artificially pressed,
or the jaws have been seriously polluted, and can no longer
continue to measure.
⑵. ―Er‖ Boot error symbol, May be pressing trigger when boot or
jaw has been opened.
⑶. Symbol of low battery & voltage: when the battery vol-
tage is lower than 5.3V, the symbol shows. At this time, it
cannot guarantee accuracy of the measurements. Batteries
should be replaced.
⑷. "OL Ω" symbol indicates that the measured resistance has
exceeded the upper limit of the Meter.
⑸. "L0.01Ω" symbol indicates that the measured resistance has
exceeded the lower limit of the Meter.
⑹. "OL A" symbol indicates that the measured current has ex-
ceeded the upper limit of the Meter.
⑺. Alarm symbol: when the measured value is greater than
the critical value of alarm setting, the symbol flashes, and the
meter issued by intermittent "beep--beep –beep--" sound.
⑻. MEM Symbol of full data storage: memory is full of data units
of 99, and can no longer continue to store data. MEM symbol
flashes.
⑼. MR Symbol of access to data: to display in an access to data,
also including the number of data.
⑽. NOISE signal: when the symbol flashes, in the measurement
of grounding resistance at a greater interference current in
the loop. At this time it cannot guarantee accuracy of the
