The hold feature freezes the display for later view. Press the HOLD button momentarily to
toggle the hold feature.
Relative Zero ( ) mode
Relative Zero allows the user to offset the meter consecutive measurements with the
displaying reading as the reference value. Practically all displaying readings can be set as
relative reference value including MAX/MIN/AVG feature readings. Press the button for
one second or more to toggle Relative Zero mode.
Manual or Auto-ranging
For most auto-ranging functions (LCD turns on by default), press the RANGE button
momentarily to select manual-ranging override. The meter will remain in the range it was in,
the LCD turns off. Press the button momentarily again to select the next range. Press
and hold the button for 1 second or more to resume auto-ranging.
Note: Manual-ranging feature is not available to AutoV, Capacitance & Hz functions.
Beep-Jack™ Input Warning
The meter beeps as well as displays "InEr" to warn the user against possible damage to the
meter due to improper connections to the A, mA, or A input jacks when another function,
especially a voltage function, is selected.
Intelligent Auto-Power-Off (APO)
The Auto-Power-off (APO) mode turns the meter off automatically to extend battery life after
approximately 32 minutes of no specified activities, where applicable:
1) Rotary switch or push button operations
2) Significant measuring readings of above 8.5% of ranges
3) Non-OL readings for Resistance, Continuity or Diode function
4) Non-zero readings for Hz function
5) Electric field signal present for EF function
6) Significant movement indication as in Phase Rotation functions
In other words, the meter will intelligently avoid entering the APO mode when it is under
normal measurements. To wake up the meter from APO, press the SELECT button
momentarily and release, or turn the rotary switch OFF and then back on. Always turn the
rotary switch to the OFF position when the meter is not in use
