To adjust the calibrator, follow these steps:
1. Enter the pressure zeroing menu.
2. Select [ZERO ]. [SET REFERENCE ABOVE] will
appear. Enter the pressure using the keypad.
3. The calibrator stores the Barometric zero offset in non-
volatile memory.
The zero offset is stored for one absolute pressure module at a
time. If a new absolute module is connected this process must
be repeated.
4. Using Source Modes (Lower Display)
The calibrator can generate calibrated signals for testing and
calibrating process instruments. It can source voltages, currents,
resistances, frequencies, pulses, and the electrical output of RTD
and thermocouple temperature sensors.
4.1 Setting 0% and 100% Output Parameters
To set the 0% and 100% points, use the following steps:
1. Select the lower display [LOWER] from Main Menu, and choose
the desired primary parameter.
2. Select output [OUT] from the input/output control, and enter the
desired value. For example select [VOLTS OUT].
3. Enter 5V with the keypad and press Enter.
4. Press any one of the four cursor control arrows to display the
setpoint control menu.
5. Hold down the Function Key that corresponds to 0% [F1]. 0%
will flash and the setpoint is stored.
6. Repeat these steps, entering 20V and holding the Function Key
that corresponds to 100% [F3].
7. Use the 25% key to cycle 5 V and 20 V in 25% increments.
