What to do if power measurement value is strange on Hioki PW3390?
If you observe a strange power measurement value, ensure that the wiring is correct. Also, verify that the rectification method and LPF (Low-Pass Filter) settings are appropriate. If the LPF is enabled, try turning it OFF.
What to do if effective power is not displayed on Hioki PW3390 Measuring Instruments?
If effective power is not being displayed, ensure that the settings for voltage range/current range and zero-suppression are correct. If the input frequency is not within the range of 0.5 Hz to 5 kHz, verify it using the noise measurement function. Also, check if the input frequency is below the lower limit setting, and verify the sync source settings and range.
What to do if voltage or current measurement values are not displayed on Hioki PW3390 Measuring Instruments?
If voltage or current measurement values are not being displayed, check the voltage measurement and current sensor cables to ensure they are properly connected and wired. Also, make sure the proper input channel is displayed. For example, if measuring input on CH1, verify that the [CH1] page is displayed.
Why is 3-phase voltage measured low on Hioki Measuring Instruments?
If the phase voltage is measured low, check if the delta-star transform function is enabled. If it is, turn OFF the delta-star transform function.
What to do if the display does not appear when you turn the power on Hioki PW3390?
If the display does not appear when you turn the power on, confirm that the power cord is properly connected.
Why are apparent power and reactive power different from other measuring devices on Hioki PW3390?
If the apparent power and reactive power of the inverter's secondary side are different from other measuring devices, and the voltage value is displayed high, ensure the rectification method is the same as other measuring devices. The calculation method may also be different, so set the calculation method to TYPE2.
What to do if current does not show 0 even with no input on Hioki PW3390?
If the current does not show 0 even with no input, and a low current range is used under the universal Clamp-on CT, it could be due to high frequency noise of the current sensor. In this case, set the LPF (Low-Pass Filter) to 100kHz and then carry out zero adjust.
What to do if keys do not work on Hioki Measuring Instruments?
If the keys do not work, hold for three seconds to disable the key-lock function.
What to do if an unusually big value is recorded in the saved data on Hioki PW3390?
If an unusually big value is recorded in the saved data, it may be because the range has been exceeded. Select an appropriate range setting.
What to do if the measurement target is a largely distorted waveform such as PWM on Hioki PW3390?
If the measurement target is a largely distorted waveform such as PWM, set the zero-crossing filter to "Strong".
