Why is the power factor error large on Mitsubishi Electric Measuring Instruments?
If input current is smaller than the rating, the error will become large (approximately 5% or less of the rated current). This is not an error. Use it as it is, or if the error is troublesome, change the CT according to the actual current.
How to troubleshoot a large analog output error in Mitsubishi Electric ME96SSRB-MB?
When the wiring with the receiver side is long, the error may become large. Execute zero/span adjustment for analog output. Refer to 4.3Test Menu 3: Zero/Span Adjustment for Analog Output.
Why is the pulse output error large on my Mitsubishi Electric Measuring Instruments?
When the pulse width is set to 0.500 s or 1.000 s, if the pulse unit is set to the minimum value, the pulse output cannot track under large load conditions, and it can result in a decrease in the pulse output number. Review the settings for pulse unit and width.
What to do if active power and power factor errors are large on Mitsubishi Electric Measuring Instruments?
The wiring for VT/CT and this instrument may be incorrect. Check the wiring for VT/CT and this instrument.
How to fix large current and voltage errors on Mitsubishi Electric Measuring Instruments?
The settings for VT/Direct voltage and CT primary current may be incorrect. Check the settings for VT/Direct voltage and CT primary current.
Why is COM blinking on the LCD of my Mitsubishi Electric ME96SSRB-MB Measuring Instruments?
Communication errors may be occurring in MODBUS RTU such as register address error or communication rate setting error. Check the register address and communication settings. If a correct MODBUS RTU communication message is received, COM will light up.
What to do if the current value measured by Mitsubishi Electric ME96SSRB-MB Measuring Instruments is different from a clamp meter?
If the comparative measuring instrument uses the average value method, the AC waveform will distort due to harmonics, and the error of the comparative instrument will become large. This Mitsubishi Electric Measuring Instruments uses the RMS value method. Compare with a current value of a measuring instrument that uses the RMS value method.
