70
HOLD
Holds measurement on display. Hold clock time will be displayed in the
right top corner.
RUN
Runs held measurement.
Selects between trending various parameters
 Δ
Shows under/over deviations measurements for all phase voltages
 Δ

voltages
METER
Switches to METER view.
TREND
Switches to TREND view (available only during recording).
Triggers Waveform snapshot.
Returns to the “MEASUREMENTS” submenu.
3.12.2 Trend
During active recording TREND view is available (see section 3.14 for instructions how to start
recording). Under deviation and over deviation parameters can be observed by cycling function key F4
(METER -TREND).
