CHROMA 16502 | mOHM METER

The measurement of micro current is easily interfered by power noise. The instrument default setting is The Chroma used advanced power noise filtering technology to filter the selected line frequency noise accordingly for accurate measurement. 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.

Setting For example, with a copper wire at an initial temperature t0 of 20? The Chroma provide temperature chrkma function. Fan and motor are combined by multiple groups of coils and should be inter-balanced between coils or it may cause abnormal sound.

It cheoma the speci?

Chroma – Milliohm Tester Updated: 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. Temperature Compensation Card A The Chroma limits this open-circuit voltage level to be lower than 20mV.

This mode is proper to be used for inductive DUT measurement which is faster because of just one level measurement. Production Testing of various inductive components coil, choke, and transformer winding etc. The fast measurement time is 65 ms.

The Chroma used advanced power noise filtering technology to filter the selected line frequency noise accordingly for accurate measurement. Delay Delay time between the test signal start output and the measurement. There are two types of PT and PT Turn on the power, and then turn the power off once you think that the increased temperature chroja the motor or coil has reached a plateau.

Delay Delay time between the test start and the external trigger. Unless rejected in some way, the thermoelectric EMFs can interfere with the measurement. RS transmission baud rate selection. Dry Circuit Dry circuit test limits open-circuit voltage level to avoid any damage on contact junction while initial chrkma contact for contact resistance measurement.

Conventional units chromw temperature correction using a copper wire at 20 oC, but the provides converted values regardless of material or temperature. DC test current output mode is used to fasten measurement speed for inductive DUT. The number of measurements to take then average can be set from 01 to R Scan 4 channels R scan with balance check function for fan motor combined with A option. Thus, test if the coils balance is needed. Chroma supports two common types of temperature probe, PT and PT Two setting methods are available: The limit can be set to single Upper or Lower, and both, depends on the test requirement.

Dry-circuit test current output mode is used to measure such contact resistances where the maximum open-circuit voltage must be limited to 20mV. There are, and for selecting. It suits component evaluation on production line.

The display shows the average value over a period. The measurement of micro current is easily interfered by power noise. Power Noise Filter The measurement of micro current is easily interfered by power noise.

Key Features Basic accuracy: Users just plug the temperature probe in the interface card with temperature function at back panel. 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. C, then this correction can be obtained 116502 making settings as shown below for the corrected temperature and the thermal coef?

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 avoid users complex calculation and calculation error. For measurement more accuracy, the customer can use it with temperature compensation function.

Temperature correction Temperature correction function without regard to material or temperature. This function is especially useful for verifying motor windings chrlma coils, where the maximum temperature increase needs to be determined when current is applied. 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.

Users usually get different resistance value with different ambient 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.
