4.1.6 Range (Manual & Auto)
Definition
When making measurements except CONT, DIODE and Temperature,
you can let the machine choose ranges for you, or you can select the
appropriate ranges manually by yourself. The difference between auto-
range and manual-range is the settling time. Auto-range is a
convenient way for you, but manual-range can usually speed up the
process.
If the input signal is beyond allowed range, an “OVLD” message will be
shown on the display. The thresholds of maximum/minimum readings
for each range are 120 % of the range for maximum and 10% of the
range for minimum.
Default
The default is auto-range. The user selected range is stored in volatile
memory and the default will be restored when the meter is power-off.
Please refer to
Table 2-1
on
page 24 for the factory default range
.
How to set the auto / manual range:
You can set the auto / manual range either through the front panel
operation or through the remote interface operation.
Front Panel Operation
First choose a measurement function on the front panel, then press
“AUTO” button to select auto-range feature. Or use
△
and
▽
buttons
to manually select a range. If selected range is not shown on the
bottom of the display, press round PREV or NEXT buttons until the
range information appears. The locations of these buttons are shown
with a red rectangle frame in
Figure 4-6
.
