Panel Display Shortcuts
Direct front–panel shortcuts are provided for three commonly used display
functions: ranging, digit masking and integration time.
Ranging
The multimeter’s manual range can be set directly from the
navigation keypad.
• To manually change the current multimeter range, press or . The
ManRng
annunciator will light, and the selected range (e.g. 100mV RANGE )
will be briefly displayed on the second line.
Digit Masking
The navigation keypad provides a shortcut to mask (change
the number of digits displayed) the reading on the main display, easing
readability.
• To enable digit masking during any measurement function, press
or .
DIGIT MASK

4.5
,
5.5
,
6.5
and
AUTO
) on the secondary display line. Press
or to scroll through and select one of these settings, then press
.
Integration Time (Bandwidth, Gate Time)
Four measurement functions allow
you to select the multimeter’s integration time: dc voltage, dc current,
resistance, and temperature. The ac voltage and current measurements
allow you to select the ac signal filter (bandwidth). The frequency/period
function allows you to select gate time. The navigation keypad provides a
shortcut for quickly changing these settings.
•
If the multimeter is configured to take the measurement using an
integration time in
NPLCs
, pressing or during front panel
measurement operations will increase or decrease the integration time
setting.
• If either the ac voltage or ac current measurement function is selected,
pressing
or during front panel measurement operations will
increase or decrease the bandwidth setting.
• If the frequency/period measurement function is selected, pressing
or during front panel measurement operations will increase or
decrease the gate time setting.
