Description

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

Using the available A165014 Temperature Compensation Card with the A165015 PT100 Temperature Probe, resistance 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 the temperature correction function. Temperature increase (Δt) is obtained and displayed by converting resistance measurements and ambient temperature with the 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.

The Pulsed ± function applications includes power chokes, switch/relay contacts, multi-braided twisted wires, metallic foils or other conductive materials, thermo-sensitive materials (fuse, thermistor sensor) etc. The Dry Circuit function applications include switch/relay contact, thermo-sensitive materials (fuse, thermistor sensors) etc. The DC+ function applications include high inductance DUTs, like primary of transformers (multi-turn) measurements with the Measurement Delay Function to avoid test currents that are not effected by high inductance DUTs during the test period.

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