Safety Precautions and Procedures

• This prosier multimeter is designed according with relevant clauses of IEC1010, before using, please read the following items carefully:
• Before using, please read ” user’s manual ” carefully.
• XShould check and confirm there is not damage in the instrument, the insulating barrier of test lead is intact before using. XWhile holding the test lead, should pay special attention not to hand exceeding the plastic of the testing needle root is protruding, otherwise have danger of shocking by electricity.
• XBefore opening the back cover, must pull out the test lead; After closing the back cover and screwing the screw on,can carry on measurement, otherwise have danger of being shocked by electricity.
• X In measure course, disconnect instrument input and then rotate function / range switch.
• X Never input signal electronic voltage exceeding the limited value to avoid electronic shock or damaging the instrument.
• XThe potential difference between the measurement public terminal COM and earth can’t exceed 600V to avoid electric short or damage the instrument.
• X Pay attention if the tested voltage is over DC 60V and AC 42V to avoid electric shock
• X If there is a symbol on the LCD display, it indicates low battery. Replace the battery to ensure measurement accuracy.
• X For the fuse, it must be replaced with an identical model if necessary. For the concrete specification, please see the clause of maintenance or label on the instrument board.

General Description

• XL830L series manual measuring-range digital multimeters design to be excellent,the appearance is novel and natural. The large liquid crystal screen dresses up the background clearly and make the demonstration  artistic
• All measurements are surveyed by the multimeter subtus three test inputs jack. namely use the test lead to test. Facilitates your operation and strengthen the security.

Operations instruction

1. DC Voltage measurement

   • Insert the red test lead into “V mA” socket and the black test lead into the “COM” socket .
   • Rotate”function/range switch” to “,choose the suitable range, if can’t sure, choose the highest range.
   • Connect the test leads in parallel to both ends of voltage source examined.

2. DC current measurement

   • The current less than 200mA, insert the red test lead into  “V mA” socket, the current is more than 200mA, insert the red test lead into “10A” socket, insert the black test lead into the “COM” socket .
   • Rotate “function/range switch”to “A ” position.and choose the suitable range.
   • Connect test leads in series into the electric current source examined.

3. AC voltage measurement

   • Insert the red test lead into “V mA” socket and the black test lead into the “COM” socket .
   • Rotate”function/range switch” to “ rv “,choose the suitable range,
   • Connect the test leads in parallel to both ends of voltage source examined.

4. Resistance measurement
   

   • Insert the red test lead into “V mA” socket and the black test lead into the “COM” socket .
   • Rotate”function/range switch” to choose the suitable range,
   • Connect the test lead in parallel to resistance examined.
   • When test resistance,turn off the power supply. Perform measurement after the capacitance is completely discharged.

5. Diode test

   • Insert the red test lead into “VOmA” socket and the black test lead into the “COM” socket .
   • Rotate “function / range switch “to position .
   • When test leads inconnect with resistance, instrument is in the ultral range state(only reveal high position ” 1 “).

6. Continuity test

   • Insert the red test lead into “V mA” socket and the black test lead into the “COM” socket .
   • Rotate” function / range switch to position.
   •  If the resistance examined between the two ends is less than about 300,the instrument will send out bee’s sound of chirping as the instruction.

7. Replacing the battery and fuse
   The “ displayed on the screen as for a sign of requirement for battery replacement. If “mA” range failed to be functional, check if damage occurs on the fuse. When replace, pis use the fuse with same specification.Unscrew the back-cover bolt to open the back-cover.

8. Battery test

   • Insert the red test lead into “VWmA” socket and the black test lead into the “COM” socket .
   • Rotate” function / range switch to “1.5V”position.
   • Connect the test leads to both ends of battery, then display the current.

Maintenance

Your digital multimeter is an accurate electronic instrument, should pay attention to safeguarding and maintaining

1. Don’t connect voltage higher than 600V DC voltage or 600V AC voltage.

2. ,Don’t operate it if the back-cover is not closed properly.

3. When upper left side display t:1] symbol,it indicates low power.You need replace the battery after unfix the test lead;open the back cover then replace with battery with the same specification.

4. When replace the fuse.unfix the test lead.Unscrew the
   back-cover bolt to open the back-cover.Replace with fuse with same specification and screw on the bolt to close the back-cover.

5. The specification of the fuse: 200mA/250V.

6. Remove the battery and put it in a dry, ventilating and few dust place if the instrument is not used for a long time ..

7. Do not change the internal circuit at will to avoid damage
