What to do if the measured value fluctuates on Hioki 3284?
If the measured value fluctuates, verify the stability of the measured circuit. For voltage measurements, ensure the test leads are fully connected. Also, consider the waveform, as certain frequencies, like those of inverters, may not be measurable.
Why is the measured value larger than the estimated value on Hioki Measuring Instruments?
If the measured value is larger than expected, ensure you're using the correct range. Examine the waveform using the MON output function to confirm that only the estimated frequency components are present. Verify that the counter has been reset with 0ADJ/RESET before peak measurement. Also, check for magnetic fields, electrical fields, or potential noise sources near the unit. Note that if the power supply switches from battery to AC adapter (e.g., after a blackout), the measured value might be temporarily higher than the actual value.
Why is the measured value smaller than the estimated value on Hioki 3284 Measuring Instruments?
If the measured value is smaller than the estimated value, check the clamp sensor is firmly closed and that the frequency of the measured circuit is within the specifications. Also, verify that you're using the proper mode. Ensure that the peak value and crest factor are below the circuit dynamic value provided in the specifications and that the battery warning annunciator is off. Confirm that the proper steps have been taken, according to procedure described in 2.5.1: Auto-zero adjustment function and 2.5.2: Zero-cancel correction function.
What to do if the output value is smaller than the estimated value on Hioki Measuring Instruments?
If the output value is smaller than expected, ensure the 9094 OUTPUT CORD is fully connected and that you've selected the correct output mode (REC or MON). Also, ensure that the previously selected output mode (current or frequency) is not active. Verify that the input impedance of the connected measuring instrument is at least 1 MΩ and that its mode is not AC coupling, or that the filter function is disabled.
What to do if the output value is larger than the estimated value on Hioki 3284 Measuring Instruments?
If the output value is larger than estimated, check that you've selected the proper output mode (REC or MON) and that the previously selected output mode (current or frequency) is not active. Note that the output value might shift for approximately 10 ms if the power supply changes from battery to AC adapter during MON output on current measurement or REC output on frequency measurement.
What to do if the counter doesn't become zero on Hioki 3284 Measuring Instruments?
If the counter does not reset to zero, use the auto-zero adjustment function (2.5.1) or use the zero-cancel correction function (2.5.2).
What to do if the Hioki Measuring Instruments unit turns off during use?
If the unit turns off during use, replace the battery.
What to do if indication appears and unit immediately turns off Hioki 3284 Measuring Instruments?
If an indication appears and the unit immediately turns off, replace the battery.
How to measure voltage if it cannot be measured on Hioki 3284 Measuring Instruments?
If voltage cannot be measured, check the test leads for a broken wire.
How to fix the Hioki Measuring Instruments unit if it does not come on?
If the unit does not come on, replace the battery.
