5.8. MEASure

Measure commands measure the output voltage, current, power or temperature. They trigger the acquisition of new data before returning the reading. Measurements are performed by digitizing the instantaneous output voltage, current or temperature. Output power is calculated as product of measured voltage and current. Keyword [:DC] is optional since all measurement are by default of the DC level of the signal.

5.8.1. MEASure[:SCALar]:CURRent[:DC]

Syntax	MEASure[:SCALar]:CURRent[:DC]? [<channel>]
Description	Query the current measured across the current sense resistor inside the PSU.
Parameters	Name	Type	Range	Default
	<channel>	Discrete	CH1\|CH2	–
Return	Returns the average output current in amperes as decimal number (NR2).

5.8.3. MEASure[:SCALar]:TEMPerature[:THERmistor][:DC]

Syntax	MEASure[:SCALar]:TEMPerature[:THERmistor][:DC]? {<sensor>}
Description	Query the temperature measured using the specified temperature sensors as follows: AUX – auxiliary temperature sensor connected to Arduino Shield board (can be used to monitor e.g. “ambient” or chassis temperature) CH1, CH2 – temperature sensor connected to channel power board used to regulate fan speed (if installed) BATT – isolated V/F (Voltage-to-frequency converter) temperature sensor connected to Arduino Shield board (can be used to monitor e.g. connected battery temperature during the charging cycle) All installed sensors are periodically tested. When sensor does not passed the test, programmed output current is automatically limited to value defined with ERR_MAX_CURRENT constant (conf_advanced.h). If load that draws more current then ERR_MAX_CURRENT value output current will be set to zero. BATT sensor support is not implemented yet.
Return	Returns the average temperature value in degrees Celsius (oC) as decimal number (NR2). If self-test detect selected temperature sensor failure or sensor is not installed a -240 or -241 error will be generated.
Parameters	Name	Type	Range	Default
	<sensor>	Discrete	AUX\|CH1\|CH2\|BATT	AUX
Usage example	MEAS:TEMP? AUX 39.50
Errors	-240,”Hardware error” -241,”Hardware missing”
