Setup Instructions
Power-Up Sequence:
1. Check to be sure the correct input line cord is used.
2. Connect the power input plug into its socket on the rear panel of the tester.
The SCI 290 series of testers has an automatic input voltage range selection.
3. Connect the male end of the plug to the grounded AC outlet.
4. Connect the Interlock Disable key to the Signal Input connector on the back panel of the tester. This is required in order to
run a test.
5. Turn on the POWER switch located on the lower left hand side of the front panel. Upon powering the tester up, a POWER ON
SELF TEST (POST) will automatically be performed. This test will check for the condition of the RAM chips, PCB’s and other
critical components. In addition the display will show the following message, with the actual model number and software
version number.
6. The tester will recall the last memory program that was active and the display will show the parameters that were
programmed into that memory. The tester is now ready for operation.
WARNING PLEASE BE SURE THAT THE SAFETY GROUND ON THE POWER LINE CORD IS NOT
DEFEATED AND THAT YOU ARE CONNECTING TO A GROUNDED POWER SOURCE. ALSO,
CONNECT THE REAR PANEL CHASSIS GROUND FOR ADDITIONAL SAFETY.

Getting to Know Your Tester
1. Working with Memories
The SCI 290 series of testers are equipped with 5 memory programs numbered 1 through 5. Each memory can be
connected sequentially to the next consecutive memory. Only one test type can be selected for each memory location.
However, all 5 memory locations can be programmed and the parameters will be saved in each memory. The tests loaded
in each memory location can be executed one at a time or as a sequence.
2. Perform Test Screen
The Perform Test Screen displays the
following parameters:
Follow the setup procedures to set the desired parameters. The display will show the either the Hipot test settings or the
Insulation Resistance test settings:
*The underscore character may be displayed after the memory number, i.e. M1_. This indicates that another congured test will
execute after the displayed setup has completed.
