Page 8: Operating Instruction
∝ Tilt stand 2-2 Operating Instruction 2-2-1 Ranging The meter defaults to autorange mode when you turn on the Meter. Manual ranging is available in V～, V , ohms , A～ , A frequency. To return to autorange, press for 1 second or turn the rotary switch. -
Page 9: Ac/Dc Current Measurement
2-2-4 AC/DC Current Measurements WARNING! To avoid injury, do not attempt a current measurement if the open circuit voltage exceeds the rate voltage of the meter. ⊇ Connect red test lead to the “mA / uA ”jack for Current measurements up to 400mA.( For measuring Current between 400mA to 10A , Connect red test lead to “... -
Page 10: Resistance Measurement
⊂ Connect the red test lead to the anode side and black test lead to the cathode side of the diode being tested. ⊆ Read forward Voltage( V f ) value on LCD. ∈ If the polarity of test leads are reversed with diode polarity ⊂, the digital reading show “... -
Page 11: Frequency Measurement
⊂ Remove power from the circuit being tested and discharge all capacitors. ⊆ Connect test lead to the circuit being measured. ∈ When the impedance between the test jack is lower than 40Ω,it will activate a continuous beeper ( 2KHz). Note: Continuity Test is available to check open/short of the circuit . -
Page 12: Battery Check & Replacement
3-1 Battery Check & Replacement 1. As battery power is not sufficient, LCD will display “ ”. Replacement of two new batteries type AAA 1.5V is Required. 2. Set Range Switch to “ OFF ” position .Use a screwdriver to remove the rear cover. -
Page 13: Maintenance
4.MAINTENANCE WARNING! To avoid electric shock, remove the test leads before opening the case, and close the case before using the meter. To prevent fire and possible arc-flash, use fuses with ratings shown on the back of the meter. Caution! To avoid contamination or static damage, do not touch the circuit board without proper static protection.
