DC current measurement
1. Connect the red test lead to the “V.Ω.mA” jack and the black test lead to “COM” jack.
(For measurements between 200mA and 10A, remove red lead to“10A” jack.)
2. Set the rotary switch at desired DCA position.
3. Open the circuit in which the current is to be measured, and connect test leads in series with the circuit.
4. Read current value on LCD display along with the polarity of red lead connection.
AC voltage measurement
1. Connect the red test lead to “V.Ω. mA” jack and the black test lead to the “COM” jack.
2. Set the rotary switch at desired ACV position.
3. Connect test leads across the source or load being measured.
4. Read voltage value on the LCD display.
Resistance Measurement
1. Connect the red test lead to “V. Ω. mA” 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. Connect test leads across the resistor to be measured and read LCD display.
4. If the resistance being measured is connected to a circuit, turn off power and discharge all capacitors
before applying test probes.
Diode test
1. Connect the red test lead to “V.Ω.mA” jack and the black test lead to the “COM” jack (The polarity
of red lead is positive “+”.).
2. Set the rotary switch at “ ” position.
3. Connect the red test lead to the anode of the diode to be tested and the black test lead to the
cathode of the diode.
The approx. forward voltage drop of the diode will be displayed. If the connection is reversed, only
figure “1” will be shown.
Battery & Fuse Replacement
If “ ”appears on display, it indicates that the battery should be replaced.
Fuse rarely need replacement and blow almost always as a result of operator’s error.
To replace battery & fuse (FH 500mA/500V 10A/500V) remove the 2 screws in the bottom of the case.
Simply remove the old, and replace with a new one.
Be careful to observe battery polarity.
Warning
Before attempting to open the case, always be sure that test leads have been disconnected from
measurement circuits. Close case and tighten screws completely before using the meter to avoid
electrical shock hazard.
