SAFETY INFORMATION The AC/DC clamp meter has been designed according to IEC1010 – 1 and IEC1010 – 2 – 032 concerning safety requirements for electrical measuring instruments and hand – held current clamps with an overvoltage category (CAT II) and pollution 2. SAFETY SYMBOLS Important safety information, refer to the operating manual. Dangerous voltage may be present. Earth ground. Double insulation (Protection class II).
-1• Read these operating instructions thoroughly and completely before operating your meter. Pay particular attention to WARNINGS, which will inform you of potentially dangerous procedures. The instructions in these warnings must be followed. • Always inspect your meter and test leads for any sign of damage or abnormality before every use. If any abnormal conditions exist (i.e. broken test leads, cracked cases, display not reading, etc.), do not attempt to take any measurements.
-2• Do not attempt calibration or service unless trained and another person capable of rendering first aid and resuscitation is present. GENERAL DESCRIPTION The meter is an autoranging professional AC/DC clamp meter with digital and analog display, 3200 counts and 33-segment bar graph. For measuring DC and AC voltage, DC and AC current, Resistance, Frequency, Diode and Continuity Test with battery operated. FRONT PANEL DESCRIPTION 1.
-37. “VHz” jack This is positive input terminal for volt and frequency measurement connection is made to it using the red test lead. 8. “COM” jack This is negative (ground) input terminal for all measurement modes except current. Connection is made to it using the black test lead. 9. “Ω” jack This is the positive input terminal for ohms. Connection is made to it using the red test lead. 10. FUNC.

Connect test leads across the source or load being measured. 4. Read voltage value on the LCD display along with the polarity of the red lead connection. AC VOLTAGE MEASUREMENT 1. Connect the red test lead to “VHz” jack and the black test lead to the “COM” jack. 2. Set the rotary switch at desired V~ position. 3.
As the jaw core may remain some magnetic force after using for awhile. If the display can not reach “0”, taking following process to correct it please: 1. Open the jaws several times. -62. 3. Adjusting the DCA ZERO knob, making the display is “0”. Then work again. RESISTANCE MEASUREMENT 1. Connect the red test lead to “Ω” jack and black test lead to the “COM” jack (The polarity of red lead is positive “+”). 2. Set the rotary switch at desired ”Ω” range position. 3.
The input voltage should be between 200mV and 10V rms. ac. If the voltage is more than 10V rms. reading may be out of the accuracy range. -7AUDIBLE CONTINUITY AND DIODE TEST 1. Connect red test lead to “Ω” jack, black test lead to “COM” jack. The polarity of red lead connection is positive “+”. 2. Set range switch to “ / ” position and push the FUNC. button to select audible continuity or diode test mode. 3. If audible continuity is selected, connect test leads to two points of circuit to be tested.

screws completely before using the meter to avoid electrical shock hazard. If “ ” appears on display, it indicates that the battery should be replaced. Use the following procedure to replacing the battery: -101. Disconnect test leads from any live source, turn the rotary switch to OFF, and remove the test leads from the input terminals. 2. The battery cover is secured to the bottom case by a screw. Using a screwdriver, remove the screw from the battery cover and remove the battery cover. 3.
The measuring result can be strongly deviating from the actual value. The measuring result can be strongly deviating from the actual value.
