Page 3: General
ZXR-40A Thank you very much for selecting our products! For your better use of this instrument, you are kindly requested to read this manual carefully before you use it, so as to understand its major performances and operation method. Caution: ① It is not allowed to remove the wiring and directly switch off the power supply during the measurement. -
Page 4: Performance Index
ZXR-40A is provided with panel type printer and large-capacity non-volatile memory, so the measurement results can be stored and printed out easily. With good stability in data testing, speediness and perfect repeatability, it is the best choice for the on-site measurement of DC resistance of transformer 2. -

ZXR-40A Ic: The dc current output. In case of single phase or two-phase measurement, Ia ① and Ib are current output. Uo: The input of measuring voltage. In case of single-phase measurement, ② Ua and Ub are voltage input. In case of two-phase measurement, Ua and Ub are the voltage input of the first channel;... - Page 6 ZXR-40A 2 0 0 7 . 0 1 . 0 1 Measurement method: Three phase Testing current: 20 A View Mode Current Measure 1 4 : 0 2 : 5 1 “Set” key-press: Set the current date and time. “View” key-press: View the data stored, including measurement results, testing date, tapping number and etc.

ZXR-40A returns to the initial interface, the measurement wiring may be removed. 5. Precautions When measuring the no-load voltage changing transformer, be sure to exit from the discharge before switching the tapping switch. Do not switch the tapping switch before the discharge is completed according to the discharge indication. -
