This Meter compl ies wi th the standards IEC61010-1 in pollution degree 2, overvoltage category (CAT II 1000V) and double insulation. If you can not follow up this operating instruction to use the meter and it reduces the chance to have an using protection.
- Before using the Meter and Test Leads inspect both items. Do not use the Meter and Test Leads if it is damaged or the case (or part of the case) is removed or no reaction on LCD display. Prohibited to use the meter without housing or housing without screw fix up in order to avoid possible electric shock or to avoid possible damage to the meter or to the equipment under test.
- If the damage of test leads, use only the same model number or identical electrical specifications replacement parts.
- Do not use your finger to touch on any testing cable, connector, unused terminal input or circuit during the testing stage.
- When the meter working at an effective voltage over 60V in DC or 30V rms in AC, special care should be taken for there is danger of electric shock.
- Selecting the correct terminal input and turn the rotary switch to select the measuring function. In case of no any idea on the value input of the current, just simply test from the high value to low one.
- Do not overload voltage or current on EITHER between terminal and terminal OR between terminal and grounding which indicate on meter limitation.
- The rotary switch should be placed in the right position and no any changeover of range shall be made during measurement is conducted to prevent damage of the Meter.
- Do not use or store the meter in an environment of high temperature, humidi ty, flammable and electromagnetic environment. The performance of the meter may deteriorate after dampened.
- The internal circuit of the meter shall not be altered at will to avoid damage of the meter and any accident
- Replace the battery as soon as the battery indicator “ ”Appears. With a low battery, the meter might produce false readings that can lead to electric shock and personal injury.
- Turn the meter off when it is not is use and take out the battery when not using for a long time.

Operational Measurement Guide
- Selecting the correct terminal input and turns the rotary switch to &elect the measuring function. If fail& to do that, the buzzer beep and the warning signal nash on.

10A| mAµA - DC or AC Voltage Measurement
- To avoid harms to you or damages to the Meter from electric shock, please do not attempt to measure voltagas higher than 1000 V although reading may be obtained.
- The Meter has an in put impedance of 10MO(exoeptUT802/ACV input impedance of 2MO) This loading effect can cause measurament errors in high impedance circuits and so you need to 1ake a note on it.
- DC or AC Current Measurement
- Before connecting the Meter in serial with the tasted return circuit, closed the return circuit current to avoid the danger of sparking.
- Do not use over >10A current measurement. Although the mater can work on below 20A current testing but for Iha avoiding any harms to you or damages to the Meter.
- Measuring Resistance, Diodes, Continuity or capacitance
- To maintain the measuremen1 accuracy, diS00unt circuit power and discharge all Iha high voltage capacftors during Iha measuring resistance.
- When measuring high resistance on 1MO or above, it is normal to take several seconds to obtain a stable reading. In order lo obtain stable reading, choose shorter test lead to carrying out measurement.
- The test leads and the Meter inside wire will bring around 0.10~0.20 of error 1o resistance measurement when measuring low resistance. To obtain accurate readings in low-resistance, short circuit the test leads beforehand and record the reading obtained, call this reading as X. Then use the equation: measured resistance value (Y} – {X) = accurate readings of resistance.
- During maasuramant, Diodes is in a good silicon junction drops between 500mV~800mV &Iii the normal value. The continuity measuremen1, the poles between resistance is >1000. it is a short circutt, but on the poles between resistance is s100, it is a good connection, buzzer is con1inually beep on, and the reading value is nearly to the circuit resistance value, Untt is C.
