Base Unit Voltage and Point Options

4200 with 128 points  |  C4200-LV


Expansion Boxes

4200 1500 VDC 128 points  |  4200-ELV

Increase the test points of your test system. Add up to seven expansion boxes for a maximum of 1024 test points. Seven add-ons can be mounted in one or two rows. An internal cable, CBL-1024, must be used when using seven expansion boxes.

Scripting Option

4200 Scripting Option  |  SCPT-4200

Scripting can make your tester extremely flexible and able to customize a test process to fit a unique task. Examples for using scripts:

  • Create complex tests that are easy for line workers to use.
  • Control external devices such as lamps, hold-down clamps, markers, etc.
  • Test devices such as switches, gas fuses, zener diodes, bi-color diodes, etc.
  • Verify color and lighting of LEDs.
  • Display operator prompts and messages.
  • Hipot different nets at different voltages.

PC Control Option, Data Collection and Easy-Wire

4200 PC Control, Data Collection, and Easy-Wire Software  |  SEW-4200

Allows you to control your tester with a Windows PC running Easy-Wire Software. Easy-Wire adds greater test and report control.

Data Collection Option (Available Soon)

4200 Data Collection  |  SPC-4200

Allows the 4200 to save test data which can then be imported into a spreadsheet or third party SPC data processing program. You can use the data to analyze and improve product quality or to generate reports for either your customers or in-house management team. Data collection is also required when the tester is used with Easy-Wire Software to show measured values on reports.

Performance Verification Kit (Available Soon)

4200 Performance Verification Kit  |  PCHK-4200

Allows you to verify the calibration and proper functionality of the 4250 tester. For information on tester calibration, click here.
