PEL-60-60-10 - Physical Instruments

MAX/MIN SETTING FUNCTION
The following are special PEL MAX/MIN setting that protects the load from error data entry for specific settings or
power sources that could cause damage to unit.
MAX VOLTAGE - Max V
MIN VOLTAGE - 0.000V
MAX CURRENT - Max A
MIN CURRENT - 0.0000 A
MAX RESISTANCE - Max OHM
MIN RESISTANCE - 0.00 OHM
MAX POWER - Max W
MIN POWER - 0.00 W
To change the values, press the "Utility/Local" key then use the keys to select the Max/Min Settings
function then the "ENTER" key. Use keys to select the appropriate Min/Max setting by pressing the
"ENTER key. The LCD will display the current value, press the "ENTER" key to enter a new value and press
the “ENTER” key to confirm entry. Press “CLEAR” key to escape the Max/Min Setting MODE.
STEPPING OPERATION SET-UP
WARNING
Every time the Stepping mode is enabled, it is critical that you re-enter or check for the correct number steps in
the STEP NUMBER function under Utility/Stepping mode to ovoid initiating erroneous step. If the value is
set higher than expected the system may perform previous steps that may exceed the power rating for the
application and may damage the PEL or power source.
All steps must be in the same constant mode (CV, CC, CR, and CP). Stepping error will occur
if different modes are programmed.
STEPPING FUNCTION
The PEL provides 99 points for self-program stepping capability. Parameters are entered in the UTILITY
configuration for the total number of steps to process and the number of loops that you want the steps repeat.
STEPPING:
STEP NUMBER
LOOP NUMBER
STEP NUMBER is the total number of steps in a loop process that commands the PEL to perform or
commands a specific function. For instance, the STEP NUMBER is set to 5, then the step procedure would
start from step 0 to step 5, total of 6 steps. The STEP NUMBER range is from 0 to maximum of 99.
Press the "Utility/Local" key then use the keys to select the STEP NUMBER function then the "ENTER"
key. Use keys to select the STEP number then press the "ENTER key twice to enter the value. Press
the “ENTER” key to confirm the selection. Press “CLEAR” key to escape the STEP NUMBER MODE.
LOOP NUMBER is the number of loops the step program will be repeated. The stepping function provides
loop control with LOOP NUMBER, which instructs the PEL to repeat the stepping function, based on the
LOOP NUMBER. For instance, LOOP NUMBER is set to 10 and the PEL will cycle the desired steps 10
times. If the LOOP NUMBER is 0, then PEL will cycle the stepping infinitely.
Press the "Utility/Local" key then use the keys to select the LOOP NUMBER function then the
"ENTER" key. Use keys to select the LOOP number then press the "ENTER key twice to enter the
value or use the keys to increment or decrement the value. Press the “ENTER” key to confirm the
selection. Press “CLEAR” key to escape the LOOP NUMBER MODE.
The PEL provides 99 points for self-programming capability for which parameters can be programmed in the
Utility function. This feature allows the users to create a mini program and automate the control of the PEL
without the need of computer, GPIB or RS-232 communication interface. The user is able to set Programming
Points, Loop Number, and Time Duration.
