Dry circuit test limits open-circuit voltage level to avoid any damage on contact junction while initial of contact for contact resistance measurement.
It sets the speci? Temperature correction Temperature correction function without regard to material or chro,a. Power Noise Filter The measurement of micro current is easily interfered by power noise. For measurement more accuracy, the customer can use it chromaa temperature compensation function.
The instrument default setting is Two setting methods are available: Delay time croma the test start and the external trigger. Generally used for DUT need more time for charge. Users also can key in the ambient temperature without the temperature probe to get temperature correction. 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 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. For some large inductance component testing, trigger delay time must be 166502 to delay the measurement start point till test current is ready.
Production Testing of various inductive components coil, choke, and transformer winding etc. The measurement of micro current is easily interfered by power noise. It is also possible to use the calculated value for making comparisons. 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.

For some large inductance component testing,trigger delay time must be set to delay the measurement start point till test current is ready.
Dry-circuit test current output mode is used to measure such contact resistances where the maximum 16052 voltage must be limited to 20mV. Features Specifications Options Brochures Comparisons. Chroma supports two common types of temperature probe, PT and PT 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. The fast measurement time is 65 ms. The limit can be set to single Upper or Lower, and both, depends on the test requirement.
Unknown Test Terminal 6. The temperature conversion function can not be used at the same time as the temperature compensation function. Users usually get different resistance value with chromq ambient temperature. The display shows the average value over a period. Generally used for automatic equipment timing adjustment or delay time for waiting a real leakage current.
Using the A Temperature Compensation Card with Chrpma 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.
Chroka transmission baud rate selection. The number of measurements to take then average can be set from vhroma to Corrected temperature setup value 2. R Scan 4 channels R hcroma with balance check function for fan motor combined with A option. Unless rejected in some way, the thermoelectric EMFs can interfere with the measurement. C, then this correction can be obtained by making settings as shown below for the corrected temperature and the thermal coef?
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.
Measurement values can be averaged to minimize display instability. With a basic accuracy of 0.
Generally used for DUT needs more time for charge. DC test current output mode is used to fasten measurement speed for inductive DUT.
Average Measurement values can be averaged to minimize display instability. Delay time between the test signal start output and the measurement.
