Full Adjust; Procedure Example - Fluke 700G Series Calibration Manual

1. Connect the PC to the Product with the interface cable that comes with
700G/TRACK software.
2. After all connections have been made, vent the Product to atmosphere and send this
command: OFFSET_ADJ?
3. Note the value returned.
4. For absolute units, apply a vacuum of <0.35 psiA, the applied vacuum should be used
for N in the OFFSET ADJUST command.
5. When the pressure is stable, send OFFSET_ADJ N, where N is the pressure given
from the OFFSET_ADJ? command.
6. Send the GAIN_ADJ? command.
7. Note the value returned.
8. Use an appropriate pressure standard to input a value equal or close to the noted
value. When the pressure is stable send, GAIN_ADJ N, where N is the entered
pressure.
9. Reset the power with the power button to save the calibration.
Two-point calibration is complete. Full adjustment may be used when the Product errors
are not linear.

Full Adjust

To avoid loss of data, do not use this procedure on a 700RG
gauge. To do this would over write the characterized values that
make it a reference gauge.
All calibration commands and adjustments are done with the keypad. Eight calibration
points are used in the adjustment. They go from full-scale to zero at pressures that equal
100 %, 87.5 %, 75 %, 62.5 %, 50 %, 37.5 %, 25 %, 12.5 %, and 0 % of full scale plus
vacuum.
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

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,
