When using probes, keep your fingers behind the
finger guards.
When making electrical connections, connect the
common test lead before connecting the live test lead;
when disconnecting, disconnect the live test lead
before disconnecting the common test lead.
Disconnect circuit power and discharge all high-
voltage capacitors before testing resistance,
continuity, or diodes.
Use only a single 9 V battery, properly installed in the
Meter case, to power the Meter.
Replace the battery as soon as the low battery
indicator (
B) appears to avoid false readings that can
lead to electric shock and injury.
Check Meter operation on a known source before and
after use.
When servicing, use only specified replacement parts.
Adhere to local and national safety codes. Industrial
protective equipment must be used to prevent shock
