Normal Operating Modes
After setting parameters with the LIMIT and CONFIG keys, Static mode is available for CR and
CV mode, while both Static and Dynamic modes are available for CC mode. In Dynamic mode,
settings for the T
HIGH , T LOW and slew parameters are also required, using the DYN STTING
key (12). The LOAD key (10) toggles on/off for the load to apply load the input terminals. Use
the CHAN key (2) to select a channel prior to setting load values in the different modes.
3.3.1 CC Mode
CC mode can be either static (fixed DC level) or dynamic (two levels with timing and slew
rates programmed). Dynamic mode is described in Section 3.3.4. In static mode, two levels
can be set to allow for quick switching between two current levels.
1. Press the MODE key (3), until the CC LED (3) is lit.
2. Press the PRES key (9) to view the programmed values.
3. Set the current level with the ÕÖ (13) keys to select each place-value to change,
and then press the × Ø keys (13) to set the desired current level.
4. Exit the preset mode by pressing the PRES key until its LED is not lit.
5. Press the LOAD key (10) to toggle the load off or on.
• Change the current at any time using the × Ø keys.
• View the values set by pressing the PRES key.
3.3.2 CR Mode
CR mode static (fixed DC level) mode is set similar to CC mode. However, the × key (13)
decreases
the resistance setting and the Ø key (13) increases the resistance setting.
1. Press the MODE key (3), until the CR LED is lit (3).
2. Press the PRES key (9) to view the programmed values.
3. To set the resistance level, use the ÕÖ keys (13) to select each place-value to
change, then press the × Ø keys (13) to set to the desired resistance level.
4. To exit the preset mode, press the PRES key until its LED is not lit.
5. Press the LOAD key (10) to toggle the load off or on.
• Change the current at any time using the × Ø keys.
• View the values set by pressing the PRES key.
