Local Operation 59
and the maximum voltage slew rate. The Multiple Electronic Load automatically selects the voltage slew
rate when the low resistance range is selected.
b. Set the slew rate to 0.25 V/
µ
s by pressing
c. Press and again and check that the display indicates "V:SLW 0.2500" (or the closest slew
rate step to this value for the particular module being programmed).
4. Set Transient Level - The transient resistance level is meaningful only if transient operation (described later) is turned
on. In the low range, the transient resistance level must be set to a higher level than the main resistance value. In the
middle and high ranges, the transient resistance level must be set to a lower value than main resistance value. If levels
are not set properly, transient operation will not take place.
a. Press
and note that the display indicates "R:TLV" and the maximum low range resistance
value.
b. Set the transient resistance level to 0.4 ohm by pressing
c. Press again and note that the display indicates "R:TLV 0.4000".
Note that you can use the Input ENTRY keys to increment and decrement the transient resistance level. Operation is similar
to that described above for the main resistance level.
Setting CV Values
The CV values for the selected channel are programmed by pressing the applicable FUNCTION keys and setting the desired
values using the ENTRY keys. The display identifies the selected function; for example "V:TLV" identifies the transient
voltage level.
Programming Range
The voltage values can only be programmed in one range. All voltage levels are programmed in volts and the voltage slew
rate is programmed in volts/microsecond.
Examples
The following examples illustrate how to program CV values. Before you do these examples, press
to set the CV values to their factory default values.
1. Set Main level
a. Press
and note that the display indicates "VOLT" and the maximum voltage value.
b. Set the main voltage level to 20 volts by pressing
c. Press
and check that the display indicates "VOLT 20.000".
Note that you can use the
ENTRY keys to increment ( ) or decrement ( ) the main VOLT level setting.
