Specifications - Ecom Instruments MCAL 4200 Instruction Manual

TRIG?
Returns TRIGGERED if the pulse train is running, and returns UNTRIGGERED when the pulse
train is not running. Returns NONE when the calibrator is not in pulse mode.
TSENS_TYPE
Sets the temperature sensor type to thermocouple, or to RTD for temperature measurement.
After the command add TC for thermocouple, or RTD for RTDs. For example:
TSENS_TYPE TC sets the sensor type to thermocouple
TSENS_TYPE?
Returns the type of sensor that is currently set to measure temperature, either TC or RTD.
UPPER_MEAS
Sets the measuring mode for the upper display. After the command enter DCI for mA,
DCI_LOOP for mA with loop power, DCV for volts, and PRESSURE for pressure. For example:
UPPER_MEAS DCV sets the upper display to measure volts
U_PRES_UNIT
Sets the unit for measuring pressure on the upper display. Add the unit after the command. The
available pressure units and their syntax are shown in Table 7. (Parameter Units). For example:
U_PRES_UNIT MMHG sets the pressure unit to millimeters of mercury at 0°C
VAL?
Returns the value of any measurement taking place on the upper and lower display. For example, if
the upper display is measuring 5mA, and the lower display is measuring 10V, then VAL? will return:
5.000000E-03, A, 1.000000E+01, V
ZERO_MEAS
Zeroes the attached pressure module. Enter the zeroing value in PSI after the command
when zeroing an absolute pressure module.
ZERO_MEAS?
Returns the zero offset or the reference value for absolute pressure modules.
