Notice
The tester is intended to use in compliance with the local rules of th e electrical usage and avoid
to apply at the places whi ch are inapplic able for th e use of electrics such as hospit al, gas station
etc.
To pre vent the functi onal decline or failure, the product should not be sprin kled or damped .
The exposed part of the tester should not be touched by the dust and liquid .
During transportation and use, it is highly recommended to a void the violent collision and
vibration of the tester, lest d amaging components and causing fai lure.
Don’t leave the tester alone while charging and rech argin g. If the battery is found severely h ot,
the tester shou ld be powered off fr om the electric source at once. The test should not be charged
over 8 hours.
Don’t use the tester where the humidit y is hi gh. Once the teste r is damp, power off immediately
and move away other cables connect ed.
The tester shou ld not be use in the e nvironment with the flammable gas.
Do n ot disassembly the instrum ent since no compon ent inside can be repaired by the user. If the
disassembly is necessary indeed, p leas e conta ct with the technic ian of our comp any.
The instrum ent shou ld not be used under the environment with strong electromagn etic
interference.
Don’t touch the tester with wet hands or waterish things.
Don’t use the d etergent to clean and t he dry cloth is sugges ted to use. If th e dirt is not easy t o
remove, the soft cloth with water or neutral detergent can be used., but the cloth should be
tweaked sufficiently.
About digital multimeter
Before u sin g,you must select the right input jack, function and range.
Never exceed th e protection limit values indicat ed i n specifications for each range of
measurement.
When the meter is linked to a measurement circuit, do not touch unused terminals.
Do n ot measure volt age if the volt age on the terminals exce eds 660V above e arth ground.
At the manual range, when the valu e scale to be measured is unknown beforeh and, set th e range
selector at the highest position.
Alwa ys b e c areful when working with voltages above 60V DC or 30V AC, keep fingers behind
the probe barri ers while measu ring.
Never connect the meter with any voltage source while th e function swit ch i s in the cu rrent,
resistance, capacitance, diode, continuit y, otherwise it will damage the mete r.
Never perform c apacitance measurements unless the ca pacitor to be measu red has been
discharged fully.
Never measure a ny of re sistance, capacitance, diode or continuity measu reme nts on live
circuits.
