6. Use
GENERAL
•When the range of the measured signal is unknown, start measurement
in auto-range mode, and then select range according to indicated value.
•The display shows “OL” when the present range limit is exceeded. Select
a higher range to continue measurement.
•Do not measure voltages > 600 V or current higher than 200mA
("VΩmA" jack [9]) or 10 A ("10A" jack [8]). Note that the meter can
only handle 10A for less than 15 seconds.
•The device will go in sleep mode when no activity is detected for ±15
seconds. Press any button to re-activate.
AC/DC VOLTAGE MEASUREMENT
•Connect the red test lead to the "VΩmA" jack [9] and the black lead to
the "COM" jack [7].
•Set the rotary switch [6] in the desired ACV or DCV ( , , )
position. If the voltage to be measured is unknown beforehand, set the
range switch in the highest range position and then reduce gradually until
the ideal resolution is obtained.
•When is selected, use the select button [3] to choose between AC
and DC voltage.
•Connect the test leads to the source being measured.
•Read the voltage value on the LCD display [1] along with the polarity of
the red lead connection.

AC/DC CURRENT MEASUREMENT
•Connect the red test lead to the "VΩmA" jack [9] and the black test lead
to the "COM" jack [7]. Connect the red lead to the "10A" jack [8] for
measurements between 200mA and 10A.
•Set the rotary switch [6] in the desired ACA or DCA ( , , ) and
use the select button [3] to choose between AC and DC current.
•Open the circuit in which the current is to be measured and connect the
test leads to the circuit IN SERIES.
•Read the current value and the polarity of the red lead connection on the
LCD display.

RESISTANCE
•Connect the red test lead to the "VΩmA" jack [9] and the black test lead
to the "COM" jack [7] (the red lead has a positive polarity "+").
•Set the rotary switch [3] in the "Ω" range position.
•Connect the test leads to the resistor to be measured and read the LCD
display.
•If the resistance being measured is connected to a circuit, turn off the
power and discharge all capacitors before applying the test probes.
Note: wait a few seconds for a stable reading when measuring resistors >

DIODE TEST AND AUDIBLE CONTINUITY TEST
•Connect the red test lead to "VΩmA" jack [9] and the black one to the
"COM" jack [7] (the red lead has a positive polarity "+").
•Set the rotary switch [6] in the position and use the select button
[3] to choose between diode or continuity test. Do not apply input
voltage at this setting!
•For diode tests, 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, the display will show “OL”.
•For continuity tests, connect the test leads to two points of the circuit to
be tested. If continuity exists, the built-in buzzer will sound.
Notes: forward DC current: ±0.5mA
backward DC voltage: ±1.5V
open circuit voltage: ±0.5V
buzzer sounds when resistance < 50
TEMPERATURE
•Set the rotary switch [6] in the °C/°F position and use the select button
[3] to choose between °C and °F. Do not apply input voltage at this
setting!
•Insert the cathode (black pin) in the "COM" jack [7], and the anode (red
pin) in the "VΩmA" jack [9].
•Use the other end of the thermocouple to measure temperatures.
•Do not change the probe, as this will influence measuring accuracy.
