TF2100 portable Single phase KWH meter tester is a kind of desk-top portable energy meter testing device which is equipped with a single-phase high-stability program-controlled power source and Single -phase multi-function standard meter developed and manufactured by our company. The device can be operated with keyboard to achieve simple functional tests, or control and management may be realized with personal computer. The PC tester has a complete range of test items and the testing device has such advantages as high measurement accuracy, high long-term stability, high degree of automation, wide output range, low distortion and high stability.
This single phase KWH meter tester is applicable to the testing of electronic and electro-mechanical single-phase active or reactive energy meter as well as multi-function energy meter.
This device can provide you with plenty of electrical information such as AC voltage, AC current, power factor, active power, reactive power, apparent power, frequency and etc.
One to three meters may be connected to this device with built-in or plug-in error processor.
This single phase KWH meter tester can be used for product test in such areas as product development, product maintenance, and production lines. Customer may self-develop its own automatic meter calibration software by making use of the underlying dynamic link library developed by our company.
