Model HF-15B High Frequency Spark Tester
HF-15B Instruction Manual – Page 51
It is important to inspect the electrode and electrode mounting plate
periodically for residue and wear.
Insulation and water deposits can reduce the effectiveness of the spark test. The
red electrode mounting plate may be wiped with a clean, dry cloth. Bead chain
assemblies contaminated with insulation residue should be removed from the
high voltage test module and cleaned with a wire brush. Broken safety covers
and mounting plates and electrode assemblies with worn brushes or missing
beads should be replaced immediately.
The red electrode mounting plate, clear cover, and bead chain assemblies are
subject to damage and contamination that is not always visible. They should be
replaced if current leakage occurs.
Refer to the “Troubleshooting” section for assistance with electrical problems.
