To Next PageTo Next PageWhy is the back light is not lit on Mitsubishi Electric ME96SSEA-MB Measuring Instruments?
The backlight may be set to auto off (Auto). If it turns on when you press a button, this is likely the case. When auto off is enabled, it turns off automatically after 5 minutes. You can either continue using it as is or change the setting to HoLd to keep it on continuously.
Why is the displayed active power different from the active power that is calculated by multiplying the displayed current, voltage, and power factor on Mitsubishi Electric Measuring Instruments?
If the AC of the current and voltage deteriorates due to harmonics, the displayed active power will differ from the calculated value. For AC without harmonics, they should match. Please continue using the instrument as it is.
Why does the display is not lit soon when the auxiliary power supply is impressed on Mitsubishi Electric ME96SSEA-MB?
This is normal. The display will not light immediately after the auxiliary power supply is connected. The instrument initializes its internal circuit for a few seconds. Continue using it as is.
Why is the total effective harmonics value from the harmonic current very different from the current value on Mitsubishi Electric Measuring Instruments?
If the distortion factor (content factor) is significantly over 100%, such as during measurement of the inverter secondary side output, the total effective harmonics value will differ greatly from the current value. Please check the measured item.
Why are measured values of PF including large error on Mitsubishi Electric ME96SSEA-MB?
If the input current is smaller than the rating (about 5% or below of rated current), the error becomes large. This is not an error. Either continue using it as is, or, if the error is problematic, change the CT according to the actual current being used.
Why cannot change the settings in the setting mode on Mitsubishi Electric Measuring Instruments?
If you cannot change settings in the setting mode and a blinking icon appears at the bottom of the screen, you are likely in the set value confirmation mode. Switch to the setting mode to make changes.
