3.4-1 Zeroing with Absolute Pressure Modules.
To zero, adjust the calibrator to read a known pressure, such as barometric pressure.
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
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 [CONFIG] option from the 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 [F2] key to step in either 25% or 10% increments.
4.1-1 Stepping the current output
To use the 25% function with mA output, follow these steps:
1. Select the [CONFIG] option from the main menu, and choose mA.
2. Use the 25% key to cycle between 4 mA and 20 mA in 25 % intervals.
