Large errors in current and voltage readings can occur if the settings for VT/direct voltage and CT primary current are incorrect. Please check these set values to ensure they are accurate.
What to do if “PASS 0000” appears when trying to change the setting mode on Mitsubishi Electric ME96SSEA-MB Measuring Instruments?
If “PASS 0000” appears when trying to change the setting mode, it means the password protection setting is enabled. Enter the set password to proceed. The default password is “0000”.
What to do if “PASS 0000” appears when trying to clear the energy or maximum/minimum value on Mitsubishi Electric ME96SSEA-MB Measuring Instruments?
If you see “PASS 0000” when clearing energy or maximum/minimum values, the password protection setting is active. Enter the correct password. The default password is “0000”.
Why are the current and voltage correct, but the active power and power factor have large errors on Mitsubishi Electric ME96SSEA-MB?
If the current and voltage readings are correct, but the active power and power factor show large errors, the wiring for VT/CT or the measurement instrument itself may be incorrect. Check the wiring to ensure it is properly connected.
What to do if COM in the LCD screen is blinking on Mitsubishi Electric ME96SSEA-MB Measuring Instruments?
A blinking 'COM' indicator on the LCD screen signals a MODBUS RTU® communication error. This could be due to an incorrect communication setting (slave address, baud rate, stop bit, or parity), a wrong function code, or an incorrect register address. Review these settings and correct them. When a correct query is received, 'COM' will light steadily.
What to do if the display is not lit on Mitsubishi Electric Measuring Instruments?
If the display is not lit, the auxiliary power supply may not be correctly connected to the MA and MB terminals. Impress auxiliary power supply.
Why do maximum value and minimum value changed on Mitsubishi Electric ME96SSEA-MB?
Maximum and minimum values are cleared if the settings for the phase wire, VT/direct voltage, and CT primary current are changed. Make a note of the values before changing the settings.
What to do if the values of the setting items that were not supposed to change have changed on Mitsubishi Electric ME96SSEA-MB?
Some setting items return to their default values when settings for the phase wire method, VT/direct voltage, and CT primary current are changed. Reconfigure the setting items that returned to their default values.
Why does “End” display remains on Mitsubishi Electric Measuring Instruments?
If the “End” display remains, the product is still in the setting mode. Press SET to exit.
What to do if the display becomes black on Mitsubishi Electric Measuring Instruments?
If the display becomes black, it may be due to static electricity. It should disappear after a while.
