4250 Base Unit

Base Unit Voltage and Test Points

• 1500 VDC Base Unit with 128 points (C4250-1500)
• 1500 VDC Base Unit with 64 points (C4250-1564)
• 2000 VDC Base Unit with 128 points (C4250-2000)
• 2000 VDC Base Unit with 64 points (C4250-2064)

4250 Expansion Unit

Increase the test point count in your system by adding 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.

• 1500 VDC 128 points (4250-E15)
• 2000 VDC 128 points (4250-E20)

4250 AC Option (AC1K-4250)

Adds AC high voltage capability up to 1000 VAC.

4250 Scripting Option (SCPT-4250)

Scripting can make your tester more flexible to customize a test process for a unique task. Examples for using scripts:

• Create complex tests that are easy for line workers to use.
• Provide extra control external devices such as lamps, hold-down clamps, markers, etc.
• Add flexibility when testing devices such as switches, gas fuses, zener diodes, bi-color diodes, etc.
• Interact with sensors to verify color and lighting of LEDs.
• Display operator prompts and messages.
• Hipot different nets at different voltages.

4250 PC Control  (PCC-4250)

Control the 4250 using a Windows PC running Easy-Wire software. Easy-Wire license required.

Easy-Wire Software (SOFT-EW)

Provides added capability to control the 4250 tester. 4250 PC Control required.

Cirris Server Software (LANL-EW)

Use Easy-Wire software to share test information on a network.

4250 Data Collection (SPC-4250)

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 must also be enabled to show measured values on reports when using Easy-Wire software.

4250 Performance Verification Kit (PCHK-4250)

Allows you to verify the calibration and proper functionality of the 4250 tester.

Digital IO Expansion Module (DIO-MOD)

The 4250 Tester comes standard with four inputs and six outputs. The Digital IO Expansion Module increases IO capability with 20 pins that can be configured to either inputs or outputs, and eight output-only pins. Use Digital I/O to add automation devices, such as start buttons, clamping mechanisms, status lights and audio output.
