4. User s Manual of Digital Clamp Meter I General This meter is a latest portable type 3 1 2 digit ARDCM Auto Range Data Clamp Meter of micropower launched by us It can be used to measure ACV DCV AC DC resistance diode forward voltage drop circuit continuity etc This meter has unique super thin and super small design and the Auto Power function It is characterized by exquisiteness firmness simplicity for operation and convenience for carrying thus it is a desirable tool for engineering design labs schools field operations home appliances servicing etc II Features Max allowed voltage between the measuring terminal and the ground 600V DC or 600V rms insulation level CAT II Pollution level II Range Auto Display 3 1 2 digit LCD max display 1999 full symbol display Font height 12mm Polarity Automatic polarity display Auto power off idle for 15min Key tone Full range overload protection Low battery display CJ occurs on the upper part of the LCD External dimensions 195mmx60mmx36mm Weight Approx 170 g including battery Working voltage 3V 1 5VAAAx2 Working current lt ImA Testing speed 3times s Working environment 0 C 40 C 32 F 104 F RH lt 80 III Instructions of Keys trigger mode M H Max Hold Press the key and the LCD display updates data and holds max F S Function Select Used for the ACA DCA switching and ACV DCV switching D H Data Hold Press this key
5. ame time show the current polarity of the point where the red test probe is For uA and mA level and test probe measurement if the AC to be measured is above 200mA measure it with clamp which cannot be used for DC measurement During measurement press the trigger to open the clamp to bite the load to be tested or one conductor of the power supply if two or more than two conductors are bitten the measurement will become void In order to ensure accuracy the measured conductor shall be located in the middle of the clamp The display shows the measurement result If the current is unknown before measurement set the function switch in 500A position and then gradually lower it Note When the clamp is used to measure the current above 10A the buzzer will sound which is normal Warning When the test probe is used for measurement do not input DC or AC above 200mA When the clamp is used to measure the AC about 500A do not last more than 20s In addition do not measure AC above 550A otherwise the meter may be damaged Resistance Measurement Q 1 Insert the black test probe into the COM jack and the red test probe into the V Q jack 2 Set the function switch in the Q position 3 Connect the test probe onto both ends of the resistor to be tested and read the measurement result on the display In case of open input end or overload OL will be displayed Note When 200Q is used it is necessary to short circuit the test probe to test t
