LOWER_MEAS
Sets the lower display to measure mode. The command is followed by any of the parameters
except for pulse and mA sim, which are source only. Enter DCI for mA, DCV for volts, TC for
thermocouple, RTD for RTD, FREQUENCY for frequency, and PRESSURE for pressure. For
example:
LOWER_MEAS DCV sets the lower display mode to VOLTS IN
L_PRES_UNIT
Sets the unit for measuring pressure on the lower display. Add the unit after the command.
The available pressure units and their syntax are shown in the Table 7. (Parameter Units).
For example:
L_PRES_UNIT KPAL sets the pressure unit to kiloPascals
OUT
Sets the output of the calibrator. This command may be used to output mA, volts, frequency,
temperature, and ohms. Frequency output, which is set by the command FREQ_TYPE, is
either continuous or pulse. The calibrator is automatically set to source mode when OUT is
entered. A number and its unit must follow the command. See Table 7. (Parameter Units) for a
list of available units. For example:
OUT 10 MA sets the calibrator to mA OUT mode and sets the output to 10mA.
OUT?
Returns the output of the calibrator. Using the above example, OUT? Would return:
1.000000E-02, A
PRES?
Returns the model and serial number of the attached pressure unit. Returns NONE if no
pressure unit is attached. For example:
PRES? Will return MARTEL,001PNS,3,0
PRES_UNIT?
Returns the pressure units of both the upper and the lower display. For example if the unit on
the upper display is bars, and on the lower it is psi, the command will return:
BAR, PSI
PULSE_CNT
Sets the number of pulses the calibrator will produce when it is triggered while in pulse mode.
For example;
PULSE_CNT 3000 will set the number of pulses to 3000.
PULSE_CNT?
Returns the number of pulses in the pulse train. Using the above example, the returned value
would be:
3000
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 key-
pad is totally locked out, and the user has to send the LOCAL command to get back to local
operation.
