The CHANCE
®
DC Hi-Pot Adapter is an electronic instrument and, if properly cared for, will
provide many years of trouble-free service. Keep all parts clean and dry.
Clean only with water
or a mild soap & water solution. Do not use chemical solvents.
When using soap for cleaning,
it is required to thoroughly rinse all soap residue off the unit before placing back into service.
Any remaining soap residue may allow high voltage tracking especially in the presence of high
humidity and/or moisture. Do not use CHANCE
®
Moisture Eater II wipes on any part of the DC
Hi-Pot Adapter as it will cause damage.
We recommend that every Hi-Pot Adapter be wiped clean and visually inspected for defects
daily and before each use. If any defect or contamination that could adversely affect the
proper operation, accuracy or mechanical integrity of the tool is suspected, the Hi-Pot Adapter
shall be removed from service. Before placing back into service, the meter should be properly
repaired (if necessary), cleaned, inspected, and tested for full operation.
Do not engrave on stick or Hi-Pot Adapter.
Abuse or misuse will damage the unit. Store in a
dry location, do not drop, and protect from jostling or impacts during storage, carrying, or use.
See page 10 "Specifications" for operating and storage temperatures and humidity ranges.

Be careful when handling the Hi-Pot Adapter. Do not drop or scratch the tool.
!
CAUTION
A standard Volt-Ohm Meter (VOM) will show “open” (no continuity) when measuring in
both directions across the DC Hi-Pot Adapter. This is due to the extremely high value (in
MegOhms) of the actual Rectifier diodes that are used to provide a high peak inverse
voltage (PIV) rating when exposed to High Voltage levels. It is recommended to confirm
the proper operation of the DC Hi-Pot Adapter by using the method described on page 6.
