Microtest 5238 Transformer Tester

Product Description:

5238  built-in Meter mode function will help you to save significantly on production facility cost, and because it could be used as a LCR power meter, you are able to elevate quality assurance and test method simultaneously i.e. leverage efficiency and lower facility cost.

MICROTEST transformer tester series offer exclusive fixture scan control kit that applies innovative CAT.5 network cable connection to simplify wiring structure and offer Open/Short calibration function, provide fixture zero-setting and high-frequency compensation functions to obtain higher accuracy for component testing. When the test frequency of the transformer becomes higher (higher than 200KHz), the interference from fixtures would also become bigger along with the test process going. Therefore, fixture zero-setting function is able to help the tester to acquire accurate measured values, which makes it become an indispensable device for quality assurance.

Basic Accuracy up to 0.1%

Support computer software connection and advanced software editing function

Innovative fixture zero-setting function to successfully prevent fixture interference from affecting the accuracy of measured values due to high test voltage

Able to test 30 items per second under fastest test speed. Elevate productivity significantly through auto-scan function

Paired with a 20-pin fixture to meet the test requirements for multi-pin network communication transformer

Optional 100mA DC Bias / 5×38 model is equipped with Meter Mode function / Support USB interface for data storag
