M-140 Multifunction Calibrator
MEATEST
94
Operation manual v46
<DNPD>
Represents the phase shift between the output voltage and current in degrees (DEG setting), or specified as a value
of the power factor (COS setting). “Technical Data” chapter lists the acceptable ranges.
,{LEAD|LAG}
This parameter is entered only when specifying the value of the power factor. If the value is omitted, LAG is used.
If query is sent, M140 returns the set value of the phase shift between the output voltage and current using standard
exponential format. Example: 156.3
is returned as 1.002.
Example:
POWE :PHAS 250.2 <cr> - activates the power generation mode and sets 250.2
phase shift
between the output voltage and current
POWE :PHAS ? <cr> - the calibrator returns 2.002
Example:
POWE :PHAS 0.554 ,LAG <cr> - activates the power generation mode and sets 0.554 LAG
power factor
POWE :PHAS ? <cr> - the calibrator returns 5.540000e-001,LAG
[SOUR] :POWE :VOLT [:LEVE] [:IMM] [:AMPL] (?) <DNPD>
This command sets the amplitude of the voltage for power generation. At the same time, the power generation
mode is set.
<DNPD>
Represents the voltage, expressed in Volts, used to generate the power. “Technical Data” chapter lists the
acceptable ranges.
If query is sent, M140 returns the set value of the voltage using standard exponential format. Example: 100.3V is
returned as 1.002.
[SOUR] :POWE :CURR [:LEVE] [:IMM] [:AMPL] (?) <DNPD>
This command sets the amplitude of the current for power generation. At the same time, the power generation
mode is set..
<DNPD>
Represents the current, expressed in Amperes, used to generate the power. “Technical Data” chapter lists the
acceptable ranges.
If query is sent, M140 returns the set value of the current using standard exponential format. Example: 1.3A is
returned as 1.000.
[SOUR] :EART :VOLT (?) <CPD> { ON | OFF | 0 | 1 }
This command connects or disconnects the voltage Lo terminal to/from GND terminal.
•
ON or 1 grounds the voltage output
•
OFF or 0 ungrounds the voltage output
If query is sent, M140 returns ON when the output is grounded or OFF when ungrounded.
Example:
EART : VOLT 1 <cr> - grounds the voltage output terminals
EART : VOLT ? <cr> - the calibrator returns ON or OFF
[SOUR] :EART :CURR (?) <CPD> { ON | OFF | 0 | 1 }
This command connects or disconnects the current Lo terminal to/from GND terminal.
•
ON or 1 grounds the current output
•
OFF or 0 ungrounds the current output
If query is sent, M140 returns ON if the current terminals are gronded or OFF if ungrounded.
Example:
EART : CURR 1 <cr> - grounds the current output terminals
EART : CURR ? <cr> - the calibrator returns ON or OFF
