Command notes (outputting voltage and current)
SENSe[1]:CURRent:RANGe <n>
Applies to battery channel (#1)
SENSe2:CURRent:RANGe <n>
Applies to charger channel (#2)
After specifying a current value, the instrument will go to the most sensitive range to accommodate
that reading. For example, if you are expecting a maximum current reading of 750mA, you can let
<n> = 0.75 (or 750e-3) to select the 5A range. Using the
:RANGe
command to manually select a
current range disables auto range. Another way to select a range is to use the MINimum,
MAXimum, and DEFault parameters as follows:
SENS:CURR:RANG MIN
Select the low current range (5mA) for battery
channel (#1) .
SENS2:CURR:RANG MAX
Select the high current range (5A) for charger
channel (#2 ).
SENS2:CURR:RANG DEF
Select the default current range for charger
channel (#2).
The response for
:RANGe?
query returns the selected range value, which can be 5.0000 A,
0.5000 A, 0.0500 A, or 0.0050 A on the battery channel. Charger channel returns are 5.0000 A or
0.0050 A.
SENSe[1]:CURRent:RANGe:AUTO <b>
Applies to battery channel (#1)
SENSe2:CURRent:RANGe:AUTO <b>
Applies to charger channel (#2)
This command is coupled to the
:RANGe <n>
command. When auto range is enabled, the
response for
:RANGe?
query returns the selected range value, which can be 5.0000 A, 0.5000 A,
0.0500 A, or 0.0050 A on the battery channel. Charger channel returns are 5.0000 A or 0.0050 A.
If you then disable auto range, the instrument will remain at the last selected range.
[SOURce1]:VOLTage <n>
Applies to battery channel (#1)
SOURce2:VOLTage <n>
Applies to charger channel (#2)
This command sets voltage amplitude in volts: 0 to 15 (1mV resolution).
:BOTHOUTON
:BOTHOUTOFF
Turns both power supply channels ON.
Turns both power supply channels OFF.
NOTE
If the limit setting is greater than 1A while on the 5A current range, the following
message will be briefly displayed when ranging down:
CURRENT LIMIT ON
mA RANGE <= 1A
