3.3.1.9 Measure Hold
MEASURE
HOLD
MEAS 3PHASE
Press the MEASURE/HOLD key to stop the measurement
process and hold the instantaneous value of each measured
parameter. With the exceptions of harmonics, waveform and 3-
phase, any display function may be selected during the time that
the measurement hold mode is active, and the corresponding
values observed. Harmonics, waveform, or 3-phase information
may only be displayed if the instrument was in that respective mode when
the MEASURE/HOLD key was pressed. Press the MEASURE/HOLD key
again to leave the Measurement Hold mode and resume measurements.
The display indicates whenever the Measurement Hold mode is active.
Two other methods of activating the Measurement Hold mode is by
reviewing Logged Data, or by the Timer Stop Gate (see 3.7.2.5).
3.3.1.10 CH2 Range
CH2 RANGE
CH1 RANGE
Press the CH2 RANGE key to select the operating voltage or
current range for Channel 2. The ranges are only approximate
and vary from unit to unit. Range values allow selection of
either auto range, or a fixed range made available from one of
the following groups (depending on the input mode selected):
0 – 3.5 12 – 28 96 – 224
3 – 7 24 – 56 192 – 448
6 – 14 48 – 112 384 – 750
