After the power is turned off, the device measures the change in temperature. All trademarks that appear on this website are the property of their respective owners.

C only, but the provides converted values regardless of material or temperature. The Chroma Milliohm Meter provides three kinds of mode for different type material application.

Chroma 16502 Milliohm Meter

Features Specifications Options Brochures Comparisons. Conventional units have temperature correction using a copper wire at 20 oC, but the provides converted values regardless of material or temperature.

Chroma supports two common types of temperature probe, 61502 and PT Setting For example, if the ambient temperature is 30?

The limit can be set to single Upper or Lower, and both, depends on test requirement. This mode is used to eliminate the affection of thermoelectric EMFs, and is proper to be used for low resistance measurement and conduction materials thermal characteristic analysis.

Using the A Temperature Compensation Card with A PT 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. It sets the thermal coef? There are, and for selecting.

For measurement integrity, contact to the test device is made via a 4-terminal Kelvin connection that incorporates an automatic zeroing function to compensate for lead errors. Corrected temperature setup value 2. It sets the speci? Dry Circuit Dry circuit test limits open-circuit voltage level to avoid any damage on contact junction while initial of contact for contact resistance measurement. It is also possible to use the calculated value for making comparisons. Generally used for automatic equipment timing adjustment or delay time for waiting a real leakage current.

There are two types of PT and PT Delay Delay time between the test signal start output and the measurement. This mode is proper to be used for inductive DUT measurement which is faster because of just one level measurement. Conventional units have temperature correction using a copper wire at 20? Delay time between the test signal start output and the measurement. Measurement values can be averaged to minimize display instability. The Chroma limits this open-circuit voltage level to be lower than 20mV.

Unless rejected in some way, the thermoelectric EMFs can interfere with the measurement.

The instrument default setting is Average Measurement values can be averaged to minimize display instability. However, for anti-static electric materials, upper than the lower limit of leakage current or cgroma the upper and lower limits is pass.

Pulsed test current output mode cbroma used to reduce thermal EMFs affection on milliohm measurement. Chroma – Milliohm Tester Updated: The Chroma used advanced power noise filtering technology to filter the selected line frequency noise accordingly for accurate measurement. Users also can key in the ambient temperature without the temperature probe to get temperature correction.

DC test current output mode is used to fasten measurement speed for inductive DUT. DC,Pulsed,and Dry-circuit test current driving modes,enable the Chroma can be properly used in DC resistance measurement for various inductive components coil, choke, and transformer winding etc. Dry-circuit test current output mode is used to measure such contact resistances where the maximum open-circuit voltage must be limited to chrroma.

With a basic accuracy of 0. The Chroma provide menu type front chgoma with LCD Display, and the programming assures that low resistance measurements can be made quick and easy.

Temperature Compensation Card A For some large inductance component testing, trigger delay time must be set to delay the measurement start point till test current is ready.

This function display the temperature t or vhroma in temperature. C, then this correction can be obtained by making settings as shown below for the corrected temperature and the thermal coef?

Setting For example, with a copper wire at an initial temperature t0 of 20? Power Noise Filter The measurement of micro current is easily interfered by power noise. Generally used for DUT needs cheoma time for charge. The display shows the average value over a period. The number of measurements to take then average can be set from 01 to The device then calculates and displays the increase in temperature. A beeper volume selection. RS transmission baud rate selection.

The measurement of micro current is easily interfered by power noise. Delay time between the test start and the external trigger. For example, for general insulation material and capacitor, lower than the upper cchroma of leakage current is Pass.

Unknown Test Terminal 6. PT Temperature Probe A Allow the motor or coil to reach room temperature, and then measure the resistance r0 and ambient temperature t0 before supplying power to the motor or coil.
