Unpacking Inspection Open the package case and take out the Meter. Check the following items carefully to see any missing or damaged part. If you find any missing or damage, please contact your dealer in your country. Operating Manual 1 piece Test Lead 1 pair Alligator Clip 1 pair K Type Temperature Probe 1 piece ( For the temperature under 230testing) Multi-Purpose Socket 1 piece Power Cord 1 piece (AC220V 50Hz DC9V/200mA) Safety Information This Meter complies with 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. 1. 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. 2. If the damage of test leads, use only the same model number or identical electrical specifications replacement parts. 3. Do not use your finger to touch on any testing cable, connector, unused terminal input or circuit during the testing stage 4. 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. 5. 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. 6. Do not overload voltage or current on EITHER between terminal and terminal OR between terminal and grounding which indicate on meter limitation. 7. 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. 8. Do not use or store the meter in an environment of high temperature, humidity, flammable and electromagnetic environment. The performance of the meter may deteriorate after dampened. 9. The internal circuit of the meter shall not be altered at will to avoid damage of the meter and any accident 10. 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. 11. Turn the meter off when it is not is use and take out the battery when not using for a long time. General Specifications 1.

Selecting the correct terminal input and turns the rotary switch to select the measuring function. If fails to do that, the buzzer beep and the warning signal flash on. Range Alarm Alert On False Terminal Input V Hz mAA hFE F 10A mAA 10A 10A mAA 2.DC or AC Voltage Measurement To avoid harms to you or damages to the Meter from electric shock, please do not attempt to measure voltages higher than 1000 V although reading may be obtained. The Meter has an input impedance of 10M(exceptUT802/ACV input impedance of 2M) This loading effect can cause measurement errors in high impedance circuits and so you need to take a note on it. 3.DC or AC Current Measurement Before connect the Meter in serial with the tested return circuit, closed the return circuit current to avoid the dangerous of sparking. Do not use over >10A current measurement. Although the meter can work on below 20A current testing but for the avoiding any harms to you or damages to the Meter. 4.Measuring Resistance, Diodes, Continuity or Capacitance To maintain the measurement accuracy, discount circuit power and discharge all the high voltage capacitors during the measuring resistance. When measuring high resistance on 1M or above, it is normal to take several seconds to obtain a stable reading. In order to obtain stable reading, choose shorter test lead to carrying out measurement. The test leads and the Meter inside wire will bring around 0.10.2 of error to 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 measurement, Diodes is in a good silicon junction drops between 500mV800mV as the normal value. The continuity measurement, the poles between resistance is >100. it is a short circuit, but on the poles between resistance is 10, it is a good connection, buzzer is continually beep on, and the reading value is nearly to the circuit resistance value, Unit is .
