Product Overview

CHROMA 16502

The Chroma 16502 Milliohm Meter is Chroma's newest digital Milliohm Meter (successor to the Quadtech LR2000). The 0.001mΩ to 1.9999MΩ wide measurement range and DC, Pulsed, and Dry-circuit test current driving modes, enable the Chroma 16502 to be used in DC resistance measurement for various inductive components (coil, choke, and transformer winding etc.), cable, metallic contact (connector, relay switch etc.) and conduction materials.

Using the A165014 Temperature Compensation Card with A165015 PT100 Temperature Probe, res i s tance values measured at ambient temperature can be corrected by applying a thermal coefficient so that the display shows the corresponding resistance values at any other temperature with temperature correction function. Temperature increase (Δt) is obtained and di splayed by conver t ing res i s tance measurements and ambient temperature with convenient temperature conversion function. This function is especially useful for verifying motor windings or coils, where the maximum temperature increase needs to be determined when current is applied.

Pulsed ± function application includes power choke, switch/Relay contract, multi-braided twisted wires, metallic foil or conductive material, thermo-sensitive material (fuse, thermistor sensor) etc. Dry Circuit function application includes switch /relay contract, thermo-sensitive material (fuse, thermistor sensor) etc. DC+ function app lication includes high inductance DUT, like primary of transformer (multi-turn) measurement with Measurement Delay Function to avoid the test current not produced that effect by high inductance DUT during test period.

Standard RS-232 interface, optional GPIB & Handler inter face, high speed and stable measurement capabilities enable the Chroma 16502 can be used for both component evaluation on the production line and milliohm measurement for bench-top applications.

The Chroma 16502 is typically used for the following applications:

  • Production Testing of Contact Resistance of Switches, Relays, Connectors, Cables, and Other Low Resistance Devices
  • Testing of Low Value Resistors, Fuses, Squibs, and Heating Elements
  • Winding Resistance of Motors, Transformers, Solenoids, and Ballasts
  • Conductivity Evaluation in Product Design
  • Incoming Inspection and Quality Assurance Testing
