Name of Parts & Position:Safety InformationRead the operating instructions and follow all safety instructions before using this instrument.Do not operate the tester if the body of meter or the current probe looks broken.Check the main function dial and make sure it is at the correct position before each measurement.Always de-energize the circuit under test before installing flexible probe measuring head. Always inspect the electronics unit, connecting cable, and flexible probe for damage before using this product.Exercise extreme caution when measuring live system with voltage greater than 60V DC or 30V AC.To avoid false readings, replace the battery as soon as possible, when “ ” symbol appears.Always wear protective clothing and gloves if hazardous live parts are present in the installation where the measurement is carried out.Never use the probe on a circuit with voltages higher than 600 V CATIII.CATIII equipment is designed to protect against transients in equipment in fixed equipment installations, such as distribution panels, feeders and short branch circuits, and lighting systems in large buildings.456Data hold buttonMIN/MAX buttonBacklight buttonEnvironmental Conditions:Altitude up to 2000 meters.Operating temperature/humidity: 0°C~50°C, <80% RH, non-condensing243Read first, to ensure safe operating and service of this current clamp, follow these instructions: Explanation of Symbols:Attention! Refer to operation instructions.Do not apply around or remove from HAZARDOUS LIVE conductors.Product is protected by double insulation.Conforms to relevant European standardsMaintenanceWARNING & !CAUTIONBefore opening the battery door, disconnect flexible current probe and never use the meter if the battery door is open.Always inspect the unit, connecting cable, and flexible probe for damage before use.To avoid electric shock, keep the clean and free of surface contamination.Make sure the flexible probe, connecting cable, and electronics enclosure are dry before further use.To avoid contamination or static damage, do not touch the circuit board without proper static protection.REMARK:CLEANING:Periodically wipe the case with a dry cloth and detergent. Do not use abrasives or solvents on this instrument.If the meter is not going to be used for a long time, take out the battery and do not store the meter in high temperature or high humidity environment.When taking current measurement, keep the cable at the center of the clamp to get more accurate test result.Repairs or servicing not covered in this manual should be performed only by qualified person.Storage temperature/humidity:-10°C ~ 60°C, <70% RH, battery removedPollution Degree: 22.

Do not use the flexible current probe to measure bare conductors unless wearing protective clothing and gloves suitable for high voltage work.Replacing Battery1. When the battery voltage drops below proper operation range the “ ” symbol will appear on the LCD display and the battery needs to be replaced.2. Remove the flexible current probe from any measuring object.3. Switch the main dial to “OFF”.4. Open the battery door with a screwdriver.5. Replace the old batteries with two new 1.5V (AAA Size) batteries.6. Close the battery door and fasten the screw.2 each AAA/R03 batteriesSpecificationsDigital Display:Over Load:Sample Rate:Low Power Indication:Power Source:Auto Power Off:4 digits LCD display with maximum reading 4200When the signal larger than the maximum will be shown2 times/secWhen the battery is below the proper operation range, will appear on the LCD display.UM-4 or AAA 1.5V battery x 2If there is no key or dial operation for 15 minutes, the meter will automatically power off to save battery consumption.

Measurement Setup
To activate unit, move the rotary switch from the “off” position to the required measuring range. Select the desired range. If the value of current being measured is unknown, first select the highest range and then reduce accordingly.Connect the flexible probe around the conductor (See Figure 2.)Center the conductor perpendicularly inside the flexible probe area.Observe the current value on the LCD.Disable-Auto Power Off:To disable the function, press the “Hold” button and keep it pressed while powering on the meter. The indicator will not be displayed.Dimension (Meter):120mm(L)x70mm(W)x26 mm(H); 4.7”(L)x2.8”(W)x1”(H)Probe Cable Length(s):203mm (8”)Probe Cable Diameter:5.5mm (nominal)Cable Length (Probe to Meter):1.5m (5 ft)Weight:Approx.196g (include battery)(At 23±5, ≦80 %RH, conductor located at the center of the flexible loop)°CELECTRICAL SPECIFICATION:Figure 2.
