Why does my Hioki Test Equipment show the maximum display value?
This issue can occur if there is a broken connection in a test lead or if the test leads are not securely connected. Check the continuity of the test lead with a tester. Also, check the connection between the test leads and the instrument, and check the connection of the tips of the test leads.
What to do if my Hioki Test Equipment won’t turn on?
The instrument may not turn on because the batteries are dead or have been installed improperly. Try replacing the batteries. If that doesn't work, ensure the batteries are installed in the proper orientation.
What to do if the voltage generation circuit is broken on Hioki Test Equipment?
Repair is required.
What to do if the measurement circuit is broken on Hioki IR4052 Test Equipment?
Repair is required.
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 settings data has been corrupted on Hioki IR4052?
Repair is required.
How to fix a broken protective fuse in Hioki Test Equipment?
If there is a broken connection in the protective fuse of your Hioki Test Equipment, replace the indicated fuse.
Why is the output voltage polarity reversed on Hioki Test Equipment?
The reversal of the output voltage polarity in Hioki Test Equipment is due to the characteristics of the insulation ohmmeter and does not represent a malfunction.
Why is the insulation resistance accuracy outside specifications on Hioki IR4052?
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.
What to do if Hioki IR4052 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.
