Supply Port (ATM and 3,000 psi)
Note
There is an isolation valve between the supply port on the manifold
and the supply port of the PCM. Follow directions to ensure that the
supply pressure and valve position is correct for the calibration point.
Send the
CAL:PRES6:VAL1 xx.xx
command to open the supply
isolation valve. This command will be used twice.
1. Remove all supply pressure from the supply port of the Product. See
Figure 41.
2. Use a TEE
to connect an external digital pressure device that reads in
Absolute units
to the supply line. Use this as the reference pressure.
3. Touch
Vent
and then
Enter
to vent the Product.
4. Ensure the supply line is disconnected from the supply port.
5. With the reference and supply sensor vented to atmosphere, type
