1. Safety Information
WARNING
Special attention shall be paid when using
the meter, improper use might cause an
electric shock or damage the meter. General
safety procedures shall be followed during
the use and safety measures regulated by
the instruction manual shall be completely
respected.
To fully make use of the functions of the
meter and ensure safe operation, please
carefully read and follow the use method of
this manual.
Instrument complies with safety requirements
on electronic measuring instrument of EN-61010-1,
EN-61010-2-030 and EN-61010-2-032, level II
pollution, and over-voltage standard is CAT III
1000V , CAT IV 600V. The C126 model only measures
AC current while the C128 model measures AC / DC
current.
Please observe safety operation guide, and
guarantee to use instrument in a safe manner.
1.1 Preparation
1.1.1 When use the meter, users must comply with
the standard safety rules:
- General protection against electric shock
- Prevent misuse of the meter
1.1.2 After received the meter, check if it has been
damaged during the delivery.

6
1.1.3 After been kept and delivered in shoddy
conditions, check and confirm if the meter is
damaged or not.
1.1.4 The pen-shape meter must be in good
condition. Before use, check the pen-shape
meter see if any damage to the insulation, if the
metal wire of the cable is bare
1.2 Symbol
Note (important security information, see
the Instruction Manual)
Able to be used on dangerous electrified
conductors.
Dual- insulation protection (Category II).
CAT III ,CAT IV follows the over-voltage
(Setup) level III and Ⅳof IEC-61010-1 standard
and pollution degree 2 means the impulse
withstand voltage level of protection provided.
In line with the European Union (EU) Standard
Grounded
1.3 Maintenance
1.3.1 Please do not attempt to open the bottom
case to adjust or repair the meter, such
operation could only be performed by
technicians fully aware of the meter and the
risk of electric shock

7
1.3.2 Before opening the meter case or battery
cover at the end, the pen-shape meter should
be removed from the circuit being measured.
1.3.3 o avoid electric shock that might be caused
by erroneous readings, when the meter
displays “ ” symbol, the battery should
be replaced immediately.
1.3.4 Use a damp cloth and mild detergent to clean
the meter, do not use abrasive cleaning
agents or solvents
1.3.5 Power supply of the meter should be turned
off when not in use, range switch to the OFF
position.
1.3.6 If the meter is not used for a long time,
batteries should be removed to prevent
damage to the meter.
