LOCKOUT
Sending this command sets the lockout state, when the unit is in REMOTE or goes to
remote it prohibits use of the keypad completely. The lockout state can only be
cleared by sending the LOCAL command.
LO_ERR
Sets the 0% point for the percent error mode calculation in the current engineering
units.
For example:
To set the 0% point to 20 psi send LO_ERR 20.
LO_ERR?
Returns the 0% point for the percent error mode calculation.
For example:
If the 0% point is set to 20 psi, LO_ERR? would return 2.000000E+01, PSI .
OHMS?
Returns the raw Ohm value from the RTD.
For example:
If when measuring a P100-385 at 0 degrees cel sending OHMS? would return
1.000000E+02, OHM .
PRES_UNIT
Used to set the pressure unit for the indicated display
For example:
To set the pressure unit to psi on the lower display send PRES_UNIT LOWER,
PSI.
PRES_UNIT?
Returns the pressure unit used when measuring pressure for each of the 3 displays.
REMOTE
Puts the calibrator in remote mode. From the remote mode the user can still use the
keypad to get back to local unless the command LOCKOUT was entered before
REMOTE. Than the keypad is totally locked out, and the user has to send the LOCAL
command to get back to local operation.
