Why are my Hioki ST5520-01 measured values unstable?
Unstable measured values may occur if the power frequency setting is not appropriate for your environment. To resolve this, change the power frequency setting to match your local power supply.
What to do if the key operation cannot be performed on Hioki ST5520-01?
If the key lock function is enabled, disable it. If the interlock function is set to ON, switch it to OFF.
How to fix ERR:001 on Hioki Test Equipment?
ERR:001 indicates that the upper limit value cannot be set because the lower limit value is greater than the upper limit value. To fix this, set the upper limit value to be greater than the lower limit value.
What to do if Hioki ST5520-01 Test Equipment voltage is not output?
If the voltage is not output, the probe wires may be broken. Use the contact check function or check the probe using a tester to resolve this issue.
What to do if Hioki ST5520-01 does not turn on?
If the power does not turn on, the power may not be supplied. Check the power cord to ensure it is properly connected.
Why is the set voltage not output on my Hioki ST5520-01?
If the set voltage is not being output, check the resistance of the load. The measurement current is limited to less than 2.0 mA, and the voltage cannot rise to the set voltage with a load carrying a current of 2.0 mA or more.
Why does a contact check error occur on Hioki ST5520-01?
A contact check error may occur if the probe wires are broken. Check the probe using a tester to resolve this.
Why is the comparator judgment result wrong on my Hioki ST5520-01 Test Equipment?
The comparator judgment result may be incorrect if the resistance range is not set appropriately for the lower limit value. Refer to the resistance measurement specifications and change the range accordingly.
How to fix ERR:003 on Hioki ST5520-01 Test Equipment?
ERR:003 means that the response time is set longer than the test duration. Check that the parameter range is correct.
What to do if Hioki Test Equipment control cannot be performed with EXT.I/O?
If control cannot be performed with EXT.I/O, the wiring may be incorrect. Check the input and output signals using the EXT.I/O test function.
Explains hazard levels (DANGER, WARNING, CAUTION), symbols, and measurement categories for safe operation.
Perform inspections of probes and instrument operation before first use to ensure safety and detect damage.
Avoid unstable surfaces, do not remove instrument case, and handle with care to prevent damage or injury.
Avoid shorting live lines, check cord condition, do not bend excessively, and observe connection precautions.
Connect the power cord and measurement leads following safety guidelines.
Perform checks on accessories, instrument, and insulation resistance tests before initial use.
