Setting the Limit Currents
•
Separate positive and negative current limits are available:
[LIM I POSITIVE] and [LIM I NEGATIVE] .
•
For example, to confi gure the instrument with maximum currents of
+1 Amp and -0.5 Amps, send the following two Command Packets .
Write
!001.00020
(Sets [LIM I POSITIVE] in Amps)
!101208-000.5002D
(Sets [LIM I NEGATIVE] in Amps)
•
To read the instrument’s limit current settings, the Command Type
changes from a WRITE (2) to a READ (1):
Read
!000.00022
(Reads [LIM I POSITIVE] in Amps)
!000.0002D
(Reads [LIM I NEGATIVE] in Amps)
•
[LIM I POSITIVE] ranges from +000.000 to +005.000 Amps.
•
[LIM I NEGATIVE] ranges from -005.000 to +000.000 Amps.
To Confi gure for a Resistive Heater
•
Set [LIM I POSITIVE] to +000.000 Amps to operate a resistive heater.
For complete detail about setting the Limit Current, see Chapter 2.
