If the MENU key is lit but the screen is blank, press any key.
What to do if the MENU key is lit, but the screen is blank on Hioki Measuring Instruments?
If the MENU key is lit but the screen is blank, press any key.
What to do if number of motor rotations cannot be measured on Hioki Measuring Instruments?
If the number of motor rotations cannot be measured, and the pulse output is the voltage output, note that the pulse of the open collector output cannot be detected. Select a voltage output suitable for the setting of the CH B pulse input. Also, check for noise in the pulse output by confirming the cable wiring, grounding the encoder providing the pulse output, or grounding the common side of the signal.
What to do if torque frequency input cannot be measured on Hioki Measuring Instruments?
If torque frequency input cannot be measured, verify that the frequency input voltage level and frequency are within the instrument’s valid input range. Use a torque gauge that generates 1 kHz to 100 Hz frequency output in the form of an RS-422 complementary signal.
What to do if no apparent cause can be established on Hioki PW3390 Measuring Instruments?
If no apparent cause can be established, perform a system reset. This will return all settings to their factory defaults.
