Chroma 16502 Milliohm Meter
The Chroma 16502 Milliohm Meter represents the latest advancement in digital milliohm measurement technology. With a wide measurement range from 0.001mΩ to 1.9999MΩ, this high-precision device is engineered for versatility, making it ideal for a variety of applications including testing inductive components, cables, metallic contacts, and conduction materials.
Equipped with multiple test current driving modes—DC, Pulsed, and Dry Circuit—the Chroma 16502 excels in measuring DC resistance with unmatched accuracy. Use the optional A165014 Temperature Compensation Card alongside the A165015 PT100 Temperature Probe to correct resistance values for ambient temperature, allowing you to view real-time resistance values at varying temperatures, particularly beneficial for assessing motor windings and coils.
The milliohm meter features a sophisticated pulsed function to accommodate a range of applications, including:
- Multi-braided twisted wires
- Metallic foils or conductive materials
- Thermo-sensitive materials such as fuses and thermistors
Its Dry Circuit function simplifies testing for switch/relay contracts and thermo-sensitive materials, while the DC+ feature optimizes measurements for high inductance devices, like transformer primaries, using a Measurement Delay Function to mitigate adverse effects during testing.
