Inspecting before Measurement and Verifying Operations
If ringing occurs that did not occur during voltage calibration
(1)
Master workpiece is grounded.
When the master workpiece is grounded, ringing may occur due to parasitic components of the
power cord or test lead.
Do not ground the master workpiece.
(2)
The test lead has been extended.
The longer the test lead the more the parasitic capacitance and parasitic inductance increase,
making it easy for ringing to occur.
If the user is processing the test lead themselves, make the lead as short as possible.
If replacing the test lead, recalibrate the voltages.
Ringing
(3)
Master workpiece insulation is worn.
Prepare a new master workpiece, and implement voltage calibration.
(4)
Test lead insulation is worn.
Prepare a new test lead, and implement voltage calibration.
IMPORTANT
If none of these apply, there is a risk that the instrument is damaged. Contact your authorized Hioki
distributor or reseller.
