Set Up
Chance Hot Stick Testers C403-3178 and C403-3179 both perform in the same manner. The C403-3178 is for 115V
source power only; the C403-3179, for 230V source only.
Make sure the tester power switch is on the “Off” position before connecting the unit to its correct power source.

1. Dry test:
The dry test should be conducted with the power switch in
the “DRY” position.
a. After turning the power switch to the “DRY” position
and with nothing in the open test area of the electrodes,
rotate the Zero knob until the meter needle aligns with
the line on the meter face indicated by the words “ZERO
TO LINE.”
Dry Testing
NOTICE
Before turning the power switch to the “WET or DRY” position, turn the Zero knob to
the “Zero” setting (fully counterclockwise). Damage to the meter could result if the Zero
knob is at the maximum setting (fully clockwise position) when the unit is turned on.
After turning the power switch to the “DRY” position
and with nothing in the open test area of the electrodes,
rotate the Zero knob until the meter needle aligns with
the line on the meter face indicated by the words “ZERO
TO LINE.” This is the position the meter needle should
return to after every test. Placing the Check Bar (which
is stored in the case) in the tester should result in a near
full deflection of the meter needle.

if the Zero knob is at the maximum setting (fully
clockwise position) when the unit is turned on.
Using the check bar with the power switch in the Wet
position will cause only a small deflection of the meter.
▲ DANGER
The unit tests with high voltages. Do not remove covers,
keep hands away from the underside of unit.
▲ CAUTION
Use only a properly grounded 3-wire power source.
Incorrect readings can occur when attempting to use a
