Making Basic Measurements Preparation and Caution Before Measurement : Observe the rules of Warnings and Cautions When connecting the test leads to the DUT (Device Under Test) connect the common (mA) test lead before connecting the live lead;...
Measuring Voltage ˙ Press the Function button to select the presently measuring function (AC / DC / AC+DC). ˙ Press the Function button > 1 sec to enter the auto test mode, and press again to exit this mode. ˙ The auto test mode can automatically determine the voltage / current which is AC or DC.
Measuring Current ˙ The basic operations are same as voltage function. Measuring Frequency ˙ When measuring voltage or current, press the Hz button to measuring the frequency for voltage or current. ˙ Press the Hz button again to exit this mode. High Frequency Reject (Low Pass Filter) ˙...
Measuring Resistance ˙ Press the Function button to select the presently measuring function (Ω / Continuity Check / Diode Test). Continuity Check ˙ Press the Function button to select continuity check when the rotary in resistance position. ˙ The buzzer allows you to quickly continuity tests without watching the display.
Diode Test ˙ Press the Function button to select diode test when the ro-tary in resistance position. ˙ In diode test, you can test direction and forward voltage. ˙ If the DUT was not a diode (Open, Short, Resistance or Capacitance), the display showed “-----”.
DC Current Output ˙ To use the DC current output function, turn the rotary in output position (Adjustable DC output or Auto DC output). ˙ The DC current output function has both modes: Source Mode & Simulate Mode ˙ The output mode has both types: 0-20mA & 4-20mA. That is selectable.
Source Mode ˙ When meter in the source mode, it provided internal power supply (Batteries > 4.5V) to drive the DC current output. ˙ To operate in the source mode, put the both probes in A terminal (Source +) and mA terminal (Source -). Then the meter will automatically enter the source mode.
Simulate Mode ˙ When meter in the simulate mode, it used external power supply (12V to 48V) to drive the DC current output. ˙ To operate in the simulate mode, put the both probes in mA terminal (Simulate +) and COM terminal (Simulate -). Then the meter will automatically enter the simulate mode.
Loop Power ˙ In this function, the meter provided internal power supply to output > 24V / 20mA. ˙ To operate in the loop power function, put the probes in A terminal (Source +) and mA terminal (Source -). Then the meter will automatically drive.

Auto Hold ˙ Press the A-HOLD button to start the auto hold mode, and press again to exit. ˙ In this mode, the meter show the indication “HOLD” on the display. ˙ When the difference is bigger (> 50d) than hold data, and it is also stable.
Store / Recall ˙ When blink cursor of menu is STORE, press the ENTER button to store the presently reading to memory. ˙ The meter can store maximum 100 data in the memory. ˙ You can enter the recall mode to review the stored data. ˙...
Power On Options When turn the power on, press the function button to execute the below options. Button Action Select the output type (0-20mA & 4-20mA) RANGE and set it to default. FUNCTION Disable APO. Show the firmware version. Enable / Disable the buzzer and set the ENTER option to default.
