Equipment and
conditions
To do an accurate calibration, requires:
• the calibration equipment specified in Table 10, below.
• a stable temperature environment: 20 ±1°C (68 ±2°F).
Table 10: Calibration equipment
Procedures
1. Connect the applicable calibration equipment (Table 10).
2. Menu: Set the menu option to C _ _ _ _ .
3. Set the calibration access code = last four digits of the serial
number (refer to Menu operation, page 5).
There are three calibration options (Table 11, below):
Table 11: Calibration options
Function Calibration equipment
Pressure An applicable pressure standard (primary or secondary) with a
total uncertainty of 0.01% reading or better.
Make the pressure connection to A1: item 4. Refer to menu
operations.
Volts (V) Volts calibrator.
Accuracy: 0.025% reading or better.
Make the Vout connection to A1: item 1. Refer to menu
operations
• Press this button to move to the next option without a change to
the values.
• Press this button to stop and make changes to a value.
• To return to the normal display, wait eight seconds.
Option Description
C0:
Set the necessary offset value for the instrument to give the
correct pressure related to zero:
All ranges g or sg: Zero (bar/psi);
Ranges a: Ambient pressure*
* adjustable by 5% FS; ** adjustable by 50 mV
C2:
Do a two-point pressure calibration.
All ranges g or sg: P1 = Zero (bar/psi); P2* = FS
Ranges a: P1* = Ambient pressure; P2* = FS
V2:
Do a two-point voltage calibration.
All ranges: P1** = 0.1000 V; P2** = 5.0000 V
