2.3 Operating Range
Current	(1%–149%) In (In=5A);(5%-149%)In (In=1A)
Voltage	(5%-149%)Un (Un=100V, 150V, 100V/);(5%-199%)Un (Un=100V/3)
2.4 Operating Load
Current	To for Tx < 0.12 cos = 1
Voltage	a for x < 0.25VA (100V)
2.5 Polarity Error Indication
When the error exceeds 180% at 5% or more of the rated operating current (voltage), a polarity indication should occur.
Note;If the error exceeds 10% of the rated operating current (voltage) and the required polarity indication still does not appear, this indicates a software fault. Do not increase the current (voltage) further to avoid damaging the instrument.
2.6 Turns Ratio Error Indication
When the error exceeds 30% but is less than 180% of the rated operating current (voltage) at 5% or above, a turns ratio error indication should be provided.

FAQ

1)What are the features of the operating interface for the MOEORW-W8050/35 portable instrument transformer calibrator?

Answer: This device features a high-resolution large-screen LCD display (resolution 320×240 dots) with a Chinese menu interface. Its design is user-friendly, aesthetically pleasing, and easy to operate. The main interface clearly displays key parameters such as the measurement object, secondary current/voltage, and accuracy class. Parameters can be modified via buttons or a computer. Measurement modes (standalone/networked, manual/automatic) can be switched according to requirements. All operations feature on-screen prompts, ensuring low learning difficulty.

2)What safety requirements must be met when using the MOEORW-W8050/35 portable transformer tester?

Answer: Core safety requirements include:
- Use only dedicated, specification-compliant power cords;
- Do not arbitrarily plug or unplug test leads connected to live terminals;
- Prohibit operation without the instrument cover, in damp environments, or in explosive atmospheres; Use fuses of the specified type and rating; avoid touching exposed circuits or live metal parts when the device is energized; cease operation and contact the manufacturer for repair if device damage is suspected; ensure all relevant terminals are reliably grounded and use a three-pin single-phase power plug to minimize interference.

3)Can the MOEORW-W8050/35 Portable Transformer Calibrator be used independently or does it require other equipment? What measurement objects does it support?

Answer: This device can be used independently or in conjunction with the manufacturer's high-speed transformer calibration bench. Measurement objects include current transformers, voltage transformers, impedance, and admittance, meeting diverse calibration needs for characteristic parameters in power metering scenarios.
