Ⅰ.
GENERAL
The instrument is a featured , stable and security small hand-held 31/2 digital multimeter. The instrument has the
function of measuring DCV, ACV, DCA, resistance, temperature, diode positive drop and continuity test, thus it
is a portable and desirable tool for users. The operation manual includes the relevant safety information and
warning notice , Please read it carefully and strictly follow all the precautions .
Ⅱ.
OPEN-CASE INSPECTION
Open the case and take out the instrument , Please carefully check the below accessories if damaged or missing .
1.Operation manual 1 pcs
2.Test leads 1 pair
3.Holster 1 pcs
Please immediately contact with suppliers if found any missing or damaged .
III.SAFETY PRECAUTIONS
Please note the safety symbols and warning notice. This series meter designed and produced strictly follow the
electronic measurement safety requirement of GB4793.1 and safety standard of IEC61010 , meet the standard of
double insulation ,overvoltage and pollution lever II . Please follow the instructions in this manual to operate the
meter ,otherwise the performance of instruction protection may be weakened or lost .
1.Before operation , ensure that the insulation layer of test leads remains unwounded . Do not operate the meter
if test leads cable or housing insulation is obviously damaged.
2.When operating the meter , should put the finger on the back of the protection ring on the test leads.
3.Do not input a voltage over 500V between instrument terminal and ground to avoid electronic shock and the
damage of the meter .
4.Be carefully to operate when the measured voltage is higher than DC 60V and AC 42Vrms to prevent
electronic shock .
5.Don’t operate instrument if back-cover is not locked ,it has the risk of electronic shock .
6.The measured signal shouldn’t exceed specified limited value to prevent electronic shock and instrument
damage .
7. Do not change range when measuring to avoid instrument damage .
8.Do not test voltage in current terminal .
9.Use the same nominal specifications of fast fuse to replace the bad fuse .
10.Don’t alter internal wiring of the instrument to prevent damage .
11.When the LCD displays
symbol, batteries should be replaced in time to ensure the accuracy of
measurement .
12.Do not operate instrument in wet ,hot and high magnetic field. Especially don’t storage instrument in damp
environment.
13.Wipe the case with a damp cloth and detergent ,do not use abrasives and alcohol.
