Front-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 will be displayed, along with a list of
choices (3.5, 4.5, 5.5, 6.5 and AUTO) on the second display line. Press
or to scroll through and select one of these settings, and 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.
