(Headers: ON)
ON
(Headers: OFF)
Performs relay check at power on.
Sets and queries the relay check (At power on)
Queries the VA check
Syntax Query
Response
:SYSTem:TEST:VA?
<numerical value 1>,<numerical value 2>,<numerical value 3>,<numerical
value 4>,<numerical value 5>,<numerical value 6>
<numerical value 1>
= Voltage value(between L and N)(NR3)
<numerical value 2> = Current value(NR3)
<numerical value 3> = VA value(NR3)
<numerical value 4> = Voltage value(between L and G)(NR3)
<numerical value 5> = Voltage value(between N and G)(NR3)
<numerical value 6> = Judgement(NR1)
See the table below.
Function Query Conducts the VA check and returns the results.
Example Query
Response
:SYSTem:TEST:VA?
:SYSTEM:TEST:VA +100.0E+00,+12.00E+00,
+1.200E+03,+100.0E+00,+0.000E+00,0
(Headers : ON)
+100.0E+00,+12.00E+00,+1.200E+03,+100.0E+00,+0.0
00E+00,0
(Headers : OFF)
The results of the VA check are as follows :
<Voltage value>
: 100.0 V(between L and N)
<Current value> : 12.0 A
<VA value> : 1200 VA
<Voltage value> : 100.0 V(between L and G)
<Voltage value> : 0.0 V(between N and G)
<Judgement> : No error
Error An execution error occurs in the following cases :
• When the measurement mode is selected
• When a mode other than "leakage current mode" is set
Note • Use this command after executing the : MODE command to activate OFF
mode (i.e., measurement mode not selected).
• When data displayed by the instrument is "less than 0.5A," the largest value
that is less than the numeric value of the data is returned.
• When the voltage is less than 80.0 V, +9.999E+09 is returned as the VA
value, voltage (between L and G), and voltage (between N and G).
