Connections
The Product uses a ¼ inch NPT male connection in the pressure input port. Different
adapters can be necessary to connect to the pressure standard. Always make sure the
hose, tubing, and fittings. Have a rated working pressure at or above the pressure of the
unit. It is also important that there be no leaks when you calibrate the Product. Use Teflon
tape where necessary.
Enter Calibration Mode
After you have made the connections, turn on the power while you hold . Use  and
 to enter the password: 101 then push . If you went into calibration mode
correctly, the display will show CAL. The pressure value shown will be the full-scale
value of the Product. For Calibration points and their values, see Table 4.
Procedure Example
Note
This example uses a 700G07 Pressure Gauge (maximum pressure
500.00 psi). Apply the shown pressures necessary for your Product as
shown in Table 4 .
The Product will prompt you for the necessary pressure at each calibration point.
1. Use the pressure standard to output 500.00 psi (100 %). After the output is stable,
push  to continue. As the Product measures, the screen will show ———-. When
measurements are complete the screen will show the calibration value.
2. Use the pressure standard to output 437.50 psi (87.5 %). After the output is stable,
push  to continue. As the Product measures, the screen will show ———-. When
measurements are complete the screen will show the calibration value.
3. Use the Pressure Standard to output 375.00 psi (75 %). After the output is stable,
push  to continue. As the Product measures, the screen will show ———-. When
measurements are complete the screen will show the calibration value.
4. Use the Pressure Standard to output 312.50 psi (62.5 %). After the output is stable,
push  to continue. As the Product measures, the screen will show ———-. When
measurements are complete the screen will show the calibration value.
5. Use the Pressure Standard to output 250.00 psi (50 %). After the output is stable,
push  to continue. As the Product measures, the screen will show ———-. When
measurements are complete the screen will show the calibration value.
6. Use the Pressure Standard to output 187.50 psi (37.5 %). After the output is stable,
push  to continue. As the Product measures, the screen will show ———-. When
measurements are complete the screen will show the calibration value.
7. Use the Pressure Standard to output 125.00 psi (25 %). After the output is stable,
push  to continue. As the Product measures, the screen will show ———-. When
measurements are complete the screen will show the calibration value.
8. Use the Pressure Standard to output 62.50 psi (12.5 %). After the output is stable,
push  to continue. As the Product measures, the screen will show ———-. When
measurements are complete the screen will show the calibration value.
9. Use the Pressure Standard to output 0.00 psi. After the output is stable, push  to
continue. As the Product measures, the screen will show ———-. When
measurements are complete the screen will show the calibration value.
