Enter a time parameter as described above for setting a voltage or current setpoint. Enter a time duration of 0-99 hours, 59 minutes. A time duration of zero effectively disables timed run mode.
When running a timed run, the time parameter displays the time remaining in the run. When running a non-timed run, the time parameter displays the elapsed time during the run
Automatic Power-fail Restart
Automatic power-fail restart capability allows a timed run which is interrupted by loss of AC power to be restarted automatically, so that the total time programmed for the time parameter will be met. NOTE: Loss of AC power includes switching off the unit using the power switch located at the rear of the unit. When performing timed runs with power-fail restart enabled, always use the front panel controls to stop a run in progress.
To enable power-fail restart, press the top function key when in the operating mode screen (constant voltage or current). The state of power-fail restart will toggle from off to on or on to off with each keypress.
When AC power is restored during a timed run in which power-fail restart is enabled, the display will show "POWER-FAIL RESTART" for approximately 10 seconds indicating power-fail restart pending. During this time the output is not energized, to allow safely stopping the run (by pressing Run). After the power-fail restart pending delay is completed, the power supply output will ramp up to the setpoint value and the time will continue from that point. Any number of power interruptions can occur during the completion of a single run.
Cleaning
Before cleaning the unit, be sure to always turn off AC power using the switch at the rear of the unit, and then disconnecting the AC line cord. The front of the unit is sealed and can be wiped clean with any mild detergent solution. Avoid harsh cleaners or agents as they may deteriorate the surface of the tactile membrane keys.
