pressed, or the jaws have been seriously polluted, and can no
longer continue to measure.
⑵. “Er” Boot-strap error symbol, May be pressing trigger or jaw
has been opened when the power is turn on.
⑶. Symbol of low battery voltage: when the battery voltage is
lower than 5.2V, the symbol shows, 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
exceeded 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. Symbol of data storage,flashing when saving data
⑼. Review data symbol, display when viewing data, and display
the number of stored data at the same time.
⑽. symbol: This symbol flashes when there is a large
interference current in the ground loop being tested. At the
same time, the instrument sounds a “beep-beep-beep-”
prompt. At this point, the accuracy of the test cannot be
guaranteed.
