Limit Setup

Other than configuring the thermistor for temperature measurement, the other
major configuration requirement is the setting of the current, voltage and
temperature limits.
To adjust current limit, press the Parameter Select button (Figure 3.8) until the LIM
I LED is illuminated. If the thermistor constants have just been set, two presses of
the Parameter Select button will illuminate the LIM I LED, otherwise the last
accessed parameter will be illuminated after the first button press. Repeated
presses of the Parameter Select button will cycle through the different selections.
Once illuminated, press the Parameter Set button and rotate the Adjust knob to
change the current limit. The LIM I LED will flash to indicate it is in adjust mode.
Voltage and temperature limits may be set in exactly the same way as described
above. Repeatedly press the Parameter Select button until the appropriate limit is
illuminated, then press the Parameter Set button and rotate the Adjust knob to set
the appropriate value. If the Parameter Set button is not pressed within three
seconds of pressing the Parameter Select button, the display reverts to normal
operation. Pressing the Parameter Select button while in normal operational
mode will illuminate the parameter that was highlighted the last time the
parameters were adjusted, even after power cycling.

Front Panel Operation

Figure 3.8 Selecting Parameters

Repeatedly press the Parameter Select button (Figure 3.9) until the CAL T LED is
illuminated and "C1" is shown in Display 1.
Press the Parameter Set button and rotate the Adjust knob until the correct value is
shown. The value is automatically stored in nonvolatile RAM after a three second timeout
or the next step is followed.
Press the Parameter Select button again to change the displayed constant to C2.
Press the Parameter Set button again and rotate the Adjust knob to dial in the new value.
Press the Parameter Select button once again to change to constant C3. "C3" should be
shown in Display 1.
Press the Parameter Set button so the value shown in Display 2 may be changed. These
values are stored in nonvolatile RAM and will remain in effect until manually changed or a
different configuration is recalled from memory.
If the temperature measurement circuit is
to be used, the thermistor constants must
be changed from their default values. This
may be done either from the front panel or
via GPIB. To change them from the front
panel, perform the following procedure:
