Relative-Zero ( ZERO) mode
Relative-Zero allows the user to offset the meter consecutive
measurements with the main display displaying reading as the
reference value.
LCD “ ” turns on. Press the
ZERO
(
HOLD
) button for one second or more to toggle Relative-Zero
mode.
DC-Zero mode
is set instead of Relative-Zero mode, however, to only
offset the non-zero DCA residuals caused by magnetic hysteresis of
the jaws as in
DCA
&
DC+ACA
functions. Press the
ZERO
(
HOLD
)
button for one second or more to activate/ re-activate this mode. Apply
this mode before making any single DCA or DC+ACA measurement for
best measuring accuracy
. The meter shows “
dc_0
” shortly to confirm
activation before continuing measurements. The beeper will sound 3
short beeps, however, to warn for null activation if the residual is
beyond a reasonable hysteresis reading of -5 to 5 DCA.
80ms PEAK-RMS mode
Press
PEAK-RMS
button for one second or more to toggle
PEAK-RMS
mode to capture inrush current or voltage RMS values in duration as
short as 80ms. LCD
turns on. Auto-Power-Off is disabled
automatically in this mode.
Backlighted LCD display
Press the
SELECT
button for 1 second or more to toggle the LCD
backlight. The backlight will also be turned off automatically after 32

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) Significant movement indication as in Phase Rotation functions
