Why won't my Hioki Test Equipment turn on?
If your Hioki Test Equipment won’t turn on, first, replace the batteries. If that doesn't work, ensure the batteries are installed with the correct orientation.
What to do if the measured value is the maximum on Hioki IR4056?
If the measured value is shown as the maximum display value when using Hioki Test Equipment, check the continuity of the test lead with a tester. Also, verify that the test leads are securely connected to both the instrument and the measurement points.
How to troubleshoot Hioki IR4056 when unable to perform measurement?
If you are unable to perform a measurement with your Hioki Test Equipment, try turning off the MEASURE key and then pressing it again. Also, make sure to separate the measurement target from all power sources before taking measurements.
Why do the batteries run out so fast in my Hioki IR4056?
If the batteries in your Hioki Test Equipment run out immediately, replace the nickel-metal-hydride or manganese batteries with alkaline batteries.
What causes excessive variation in measured values on Hioki Test Equipment?
If you experience excessive variation in the measured value with your Hioki Test Equipment, it could be due to induced noise from a nearby charging circuit. Try disconnecting the circuit breaker for any nearby charging circuits. If this isn't possible, use the lowest measured value as your result. Another cause could be a large capacitance component in the measurement target. If possible, remove the capacitor; otherwise, use the lowest measured value.
How to measure in 500 V or 1,000 V range on Hioki IR4056?
If you are unable to perform a measurement in the 500 V or 1,000 V range on your Hioki Test Equipment, press after setting the rotary selector to the 500 V or 1,000 V range. Note that pressing while holding the MEASURE key will not disable the lock function.
Why does Hioki IR4056 Test Equipment give different readings for the same target?
If you get a different measured value each time you measure the same target with your Hioki Test Equipment, it could be due to the effects of the insulator’s polarity. Allow about 1 hour to 1 day to pass after the first measurement before repeating. Alternatively, the differences may be due to the insulator’s temperature characteristics, so measure the target under the same temperature and humidity conditions.
Why does insulation resistance increase over time on Hioki Test Equipment?
If the insulation resistance measured value increases over time on your Hioki Test Equipment, it is not a malfunction. If the measured value fluctuates gradually, wait for it to stabilize and then use that value.
What to do if Hioki IR4056 Test Equipment unable to perform zero adjustment?
If your Hioki Test Equipment was unable to perform zero adjustment (Low resistance function), verify that there is no broken connection in the test leads.
Why is the insulation resistance accuracy outside specifications on Hioki IR4056?
If, when calibrating your Hioki Test Equipment, the accuracy of the insulation resistance range falls outside the device specifications, use the test leads that came with the instrument or its optional test leads to perform the calibration procedure. The issue might be that the test lead cable insulation resistance is too low.
