Quality Assurance & Professional Services
Certified Traceability & Calibration: Our manufacturing facility maintains advanced standard resistors and high-voltage reference sources fully traceable to the National Institute of Metrology (NIM). Every MOEORW-WRZ33 unit undergoes a rigorous, multi-point, per-dial calibration process before shipment to guarantee that actual accuracy and stability exceed all published specifications.
Strict Aging & Heavy-Duty Testing: To eliminate initial component drift, all critical high-voltage resistor components undergo thorough aging screening and thermal cycling tests. Furthermore, every finished calibrator must pass a 10kV dielectric strength insulation safety test, ensuring long-term field reliability and ultimate operational safety.
ISO 9001 Quality System Control: Operating under a certified ISO 9001 quality system, our factory implements total-process control. From strict component incoming inspection to final product release, every step is fully documented to ensure peak product consistency.

Q1: Can the MOEORW-WRZ33 calibrate both electronic insulation testers and traditional hand-cranked megohmmeters?
A: Yes, absolutely. The MOEORW-WRZ33 is built with multi-functional integration to handle both electronic (digital) and analog (pointer-type) instruments. When coupled with a constant-speed drive unit (such as our optional CY3 model), it can fully verify specialized analog parameters including open-circuit voltage (Uk), mid-scale voltage (Uz), and peak voltage (Uf), as well as standard drop voltage (Ud) for digital testers.
Q2: Is the calibration data of this device fully traceable to international standards?
A: Yes. Our production facility maintains precision master references and high-voltage sources that are completely traceable to the National Institute of Metrology (NIM). The MOEORW-WRZ33 delivers laboratory-grade accuracy-achieving a 0.2-grade class on core resistance decade dials-making it fully compliant with the data traceability and audit requirements of quality management systems like ISO/IEC 17025.
Q3: How does the MOEORW-WRZ33 handle the risk of high-voltage residual charge after a calibration session?
A: Safety is a core pillar of our design. The MOEORW-WRZ33 features a dedicated "DISCHARGE" position prominently located on the front panel. Once a measurement at up to 10kV is completed, switching to this position actively and safely dissipates any residual static charge and high voltage within seconds, ensuring the operator can handle the test leads with total safety.
Q4: Can the built-in DC digital voltmeter and the high-resistance decade box be used separately for other laboratory tests?
A: Yes, they are engineered as decoupled circuits. The resistor section and the 0 to 10,000V DC voltmeter section can operate completely independently. This means you can use the decade box as a standalone high-voltage standard resistor bank or utilize the digital meter as a standalone 10kV high-precision voltmeter, maximizing your laboratory bench utility.
Q5: What standard safety and overload protections are implemented for the dial switches?
A: To eliminate human error and protect the unit, each decade dial is engraved with its precise maximum allowable operating voltage (e.g., 10kV / 2500V / 500V) or current (e.g., 8mA / 20mA / 50mA). Additionally, the internal structure boasts an ultra-high circuit-to-case insulation resistance of greater than or equal to 1 x 10^11 ohms, preventing internal breakdown during full-load high-voltage operations.
