The device then calculates and displays choma increase in temperature. 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.


cchroma When evaluating motors and coils, it is necessary to con? C, then this correction can be obtained by making settings as shown below for the corrected temperature and the thermal coef? There are two types of PT and PT However, for anti-static electric materials, upper than the lower limit of leakage current or between the upper and lower limits is pass. The display shows the average value over a period.

With a basic accuracy of 0. Chrom Testing of various inductive components coil, choke, and transformer winding etc. The fast measurement time is 65 ms. Two setting methods are available: For example, for general insulation material and capacitor, lower than the upper limit of leakage current is Pass.


The Chroma Milliohm Meter provides three kinds of mode for different type material application. It sets the speci?


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.

Four terminal test cable with Clips Distributed by: PT Temperature Probe A Measurement values can be averaged to minimize display instability.

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. The number of samples to average can be set chrkma 01 to Generally used for automatic equipment timing adjustment or delay time for waiting a real leakage current.

The provides R scan function plus option Dhroma 4 channels R scanner for customer test.

C at an ambient temperature 30? Temperature Compensation Card A 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. Delay Delay time between the test start and the external trigger.

A beeper volume selection. RS transmission baud rate selection. R Scan function should be coordinated with purchased option A 4 channels R scanner.


The Chroma limits this open-circuit voltage level to be lower than 20mV. Setting For example, chromx a copper wire at an initial temperature t0 of 20?

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.

The temperature conversion function can not be used at the same time as the temperature compensation 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. For some large inductance component testing, trigger delay time must be set to delay the measurement start point till test current is ready.

Chroma supports two common types of temperature probe, PT and PT Delay Delay time between the test signal start output and the measurement. Allow the motor or coil to reach room temperature, and then measure the resistance r0 and ambient temperature t0 before supplying power to chro,a motor or coil. Generally used for DUT need more time for charge.
