Professional Cordless Circuit Tester
1. SAFETY RULES
This circuit tester is designed for indoor use at temperatures between 0°C to 40°C
•
and altitudes up to 2,000m.
To ensure that the Circuit tester is used safely, follow all safety and operating instruc-
•
tions in this operation manual. If the tester is not used as described in this operation
manual, the safety features of this instrument might be impaired.
Do not use the tester if the instrument looks damaged ,or if you suspect that the
•
tester is not operating properly.
When using the instrument, keep your ngers on the metal barrel, between the plastic
•
parts of the body.
Make sure power is off before cutting, desoldering, or breaking the circuit wires. Small
•
amounts of current can be dangerous.
Do not use in circuits more than 28 VDC or with AC powered circuits.
•
To avoid electrical shock, use CAUTION when working above 30V DC or 25V AC
•
rms. Such voltages pose a shock hazard.
To avoid electrical shock or damage to the circuit tester meter, do not exceed the
•
input limits.

3.2 Electrical Specifications
The input voltage should not exceed the indicated values. This is to
•
prevent personal injuries and damage to the instrument.
4.2 Testing for voltage
CAUTION: Maximum Input Voltage is 28VDC, do not
exceed this rating to avoid personal injuries
or damage to the instrument
A
C
B
A - Hold tester by metal body and place free hand on a bare
(grounded) metal part of the vehicle.
B - Place tester point into connector or wire (pierce insulation if
nessesary).
C - Tester will light, buzz and vibrate when a positive voltage is
detected.
4.3 V-Groove Probe Tip Protector
To prevent injury always insert the V-Groove protector tip on
•
the tester point before carrying or storing the unit.
Use the V-grove protector tip when piercing wires to prevent
•
the tester point from side-slipping on the wire and causing
injuries or damage.
The protector tip may be removed for testing in hard to reach
•
places inside connectors, sockets, etc.
5. MAINTENANCE
5.1 Battery Replacement
The batteries supplied with the tester will provide years of service
under normal use. When the sound and light start to fade,
Remove the screw and pull out the plastic pointer assembly.
•
Extract the batteries and insert new ones “type Duracell
•
MN9100” or equivalent, observing the polarity (negative side
goes in first).
Insert tester point assembly aligning the holes and replace the
•
screw.
