Range selection
For best accuracy and resolution, always use an appropriate range to perform the measurement.
With autorange enabled, the instrument will automatically select the optimum measurement range.
Autorange is the power-on default setting.
You can select a measurement range (or autorange) in a couple of ways:
•
Use the front-panel keys to select a range or control autorange.
•
Use a configuration menu to select a range or control autorange.
The difference between autoranging and manual ranging is the settling time. Autorange is convenient,
but a manually selected range can usually speed up the process.
If the input signal exceeds the allowable range, the
OVLD
message is displayed. The threshold for
readings is 120 percent of the range for maximum and 10 percent of the range for minimum.
The measurement range for temperature, continuity, and diode testing is fixed and cannot be
changed.
Front-panel operation
Perform the following steps to set measurement range using the front panel keys:
1. Select a measurement function.
2. Select a measurement range or use autorange:
•
Use the
RANGE
▲ and ▼ keys to select a range. The MAN indicator turns on to indicate that manual
ranging is being used.
•
Pressing
SHIFT
and then
ESC
(
AUTO
) toggles the instrument between manual ranging and autorange.
When autorange is selected, the MAN indicator is off.
