Selects output mode.
Selects input mode.
Toggles between centigrade and Fahrenheit when you are using the
TC or RTD functions.
Used to enter an exponent when you define a custom RTD.
Used to recall a programmed set point.
Press
number of the output setpoint that you want to use. The output will
then be programmed to the setpoint you entered.
Used to regain local control of the calibrator. If you set the calibrator to
a remote state using the remote commands, all the front panel keys are
locked out except the Local key. When you press the Local key, the
front panel is unlocked.
This function does not work when you set the Calibrator using the Remote with
Lockout command. In Remote with Lockout mode, ALL keys are locked out and
the Local key will not unlock the front panel.
AUTOSET runs through the setpoints you entered using the SET function.
Press . AUTO SET POINT? appears on the display.
Enter a number between 1 and 9 that corresponds to the number of
setpoints being used. DWELL TIME 5-500? appears on the display.
Dwell time is the number of seconds between each setpoint. The output
cycles through each setpoint and then reverses the order. For example,
if 5 is entered for the number of setpoints, the Calibrator cycles through
setpoints1, 2, 3, 4, 5 and then reverses to setpoints 4, 3, 2, and 1.
Setpoints of 30 V or greater will not go to standby when you use
this feature.
Zeros the pressure module reading when in pressure measurement mode.
Zeros the thermocouple TC mV/°C offset when in TC measurement mode.
Press to scroll through the LCD backlight, interface, and address
menus.
• Use and to adjust LCD backlight when the LCD menu is
displayed.
• Use

SETUP
Activates/deactivates the autorange feature of the calibrator in voltage
source modes.
Used to program a setpoint step for any output mode. Key in the
desired output and press . SETPOINT # appears on the
display. Select a setpoint number from 1 to 9. The output you entered
can now be recalled or used in the AUTOSET key described later in
this manual.
Each TC type, each RTD/OHMS type, mA, and volts each have
9 programmable setpoints.
Toggles between the internal and external cold junction
reference locations.
