To Next PageTo Next PageWhat to do if I am unable to perform measurement on my Hioki Test Equipment?
If you are unable to perform a measurement with your Hioki Test Equipment, first turn off the MEASURE key and then press it again. Also, ensure that the measuring object is separated from all power sources before you attempt to measure it.
How to fix Hioki IR4053 when the power is not turning on?
If your Hioki Test Equipment is not turning on, replace the batteries with new ones and ensure they are installed in the correct orientation.
Why do the batteries in my Hioki IR4053 run out so quickly?
If the batteries in your Hioki Test Equipment run out immediately, replace them with alkaline batteries.
What to do if my Hioki IR4053 shows the maximum display value?
If the measured value on your Hioki Test Equipment is shown as the maximum display value, check the continuity of the test lead with a tester. Also, check the connection between the test leads and the instrument, and the connection of the tips of the test leads.
What should I do if the protective fuse has tripped in my Hioki IR4053 Test Equipment?
If the protective fuse in your Hioki Test Equipment has tripped, replace it with the indicated fuse.
How to fix Hioki IR4053 when unable to perform measurement in 500 V, 1000 V or PV range?
If you are unable to perform measurements in the 500 V, 1000 V, or PV range on your Hioki Test Equipment, release the lock function.
What to do if the MEASURE key is not working for the lead with a switch on my Hioki IR4053 Test Equipment?
If the MEASURE key is not working for the lead with a switch on your Hioki Test Equipment, ensure that you fully insert the plug to the limit without any gaps.
Why does the MEASURE key enable the lock function after releasing it in Hioki IR4053?
If, in the 500 V, 1000 V, or PV range, turning on the MEASURE key enables the lock function that has been released on your Hioki Test Equipment, replace the batteries with new alkaline batteries and release the lock function again.
How to stabilize measured values on Hioki IR4053 Test Equipment?
If the measured values from your Hioki Test Equipment vary and fail to stabilize, disconnect the circuit breaker for any nearby charging circuits. If this is not possible, use the lowest measured value as the measurement result.
Why do measured values fluctuate over time on Hioki IR4053 during insulation resistance measurement?
When measured values acquired through insulation resistance measurement or PV measurement fluctuate over time on your Hioki Test Equipment, if it is possible to remove the capacitor, do so. If not, use the lowest measured value as the measurement result. Alternatively, select measured values acquired one minute after the start of the measurement, or after they have stabilized if a large capacitance component is included.
