Automated Testing

Storing Test Setups
1. Set the Voltage and Current values as desired.
2. Press the SEC button and set the time in seconds. This time will be associated with the
step if the automatic step output function is selected.
3. Press the STORE button to save the values. "STRxxx?" will appear in the display
(where "xxx" (0 to 199) will be the memory location).
4. Press ENTER to store the value in the displayed location or enter a new location
number from the keypad and press ENTER. If a three digit number is entered, pressing
ENTER is not necessary.
Recalling Test Setups
1. Press the RECALL button to view the setup in a memory location. "RCLxxx" and the
stored values will appear in the display (where "xxx" (0 tp 199) will be the memory
location).
2. To view the setup in any other location, enter the setup number and press ENTER. If a
three digit number is entered, pressing ENTER is not necessary.
3. Press RECALL to exit the display.
Automatic Test Sequencing (ATS)
In ATS mode, the unit automatically cycles through a series of stored test setups. The first
and last steps are programmable and the sequence will include all steps between the first
and last steps. Each test setup memory location represents one step. The duration the step
is programmable from 0.01 to 60 seconds and is programmed when the steps are stored.
Note: Initial setup and sequencing should be performed in the STBY mode to verify proper
operation without an active output.
Setup and Operation of Automatic Test Sequencing (ATS)
1. To set the LAST and FIRST step of the sequence:
a. Press the RECALL button.
b. Use the numeric keypad to enter the three digit test setup location number for the
last step (RCL018, for example) and press ENTER.
c. Use the numeric keypad to enter the three digit test setup location number for the
first step (RCL001, for example) and press ENTER.
d. Press RECALL
2. The time duration for each step is stored with each step in the storing process.
3. To begin the test sequencing, press and hold the RECALL until the beeper sounds and
the stair-step icon appears. The sequencing will automatically begin a single cycle
through the programmed steps.
4. Observe the output for proper operation.
5. Press the OPER/STBY key to activate the output
6. Press the OPER/STBY to return to the standby mode or press CE to exit the sequencing
mode
Note: The ATS session will be terminated if any command is received via the RS-232c
interface.
Note: For continuous cycling, hold the RECALL button while turning power on.
