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 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, 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 temperature correction function. Temperature increase (?t) is obtained and displayed by converting resistance 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 contact, multi-braided twisted wires, metallic foil or conductive material, thermo-sensitive material (fuse, thermistor sensor) etc.
Dry Circuit function application includes switch/relay contact, thermo-sensitive material (fuse, thermistor sensor) etc.
DC+ function application 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 RS232 interface, optional GPIB & Handler interface, 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.
