4-8 Operation
To set the maximum output current limit press Max Settings . The first maximum setting screen appears as a prompt for
the maximum output current limit.
Maximum Settings
Enter a Value For
Max Current: 60.0000 A
Use the data entry keys to enter the maximum output current limit value between 0.0000 and 60.0000 A. Press Enter to
accept the new value. Press Escape to restart the setting sequence and enter a different value. Press Escape again to
leave the setting sequence.
NOTE: The maximum output current limit value can be set as high as 60.1000 A. This can be used to compensate for
current loss due to high resistance leads and for variances in calibration. The output current is guaranteed to
reach a minimum of 60 A but may not be able to reach 60.1 A in all circumstances.
4.11.2 Maximum Compliance Voltage Limit
The maximum compliance voltage limits, in magnitude, the maximum compliance voltage that can be entered.
To enter a value for the maximum compliance voltage limit, continue from the maximum output current limit screen or
press
Max Settings then Enter until the following display setup screen appears as a prompt for the maximum
compliance voltage limit.
Maximum Settings
Enter a Value For
Max Voltage: 5.0000 V
Use the data entry keys to enter the maximum compliance voltage limit value between 0.1000 and 5.0000 V. Press Enter
to accept the new value. Press Escape to restart the setting sequence and enter a different value. Press Escape again to
leave the setting sequence.
4.11.3 Maximum Current Ramp Rate
The maximum current ramp rate limits the maximum current ramp rate that can be entered. If ramp segments are being
used, this setting will also limit the ramp rate that can be set by a ramp segment. Refer to Paragraph 4.12 to setup Ramp
Segments.
To enter a value for the maximum current ramp rate limit, continue from the maximum compliance voltage limit screen
or press
Max Settings then Enter until the following display setup screen appears as a prompt for the maximum current
ramp rate limit.
Maximum Settings
Enter a Value For
Max Ramp Rate: 1.0000 A/s
Use the data entry keys to enter the maximum current ramp rate limit value between 0.0001 and 99.999 A/s. Press Enter
to accept the new value. Press Escape to restart the setting sequence and enter a different value. Press Escape again to
leave the setting sequence.
