Push this button to select AC/DC Voltage measuring function
when the function switch is set at “V” positions
Push this button to select AC/DC current measuring function when
the function switch is set at uA, mA, 20A positions.
Push this button to select Ohm/diode/continuity /Capacitance
measuring function when the function switch is set at
Ohm/diode/continuity /Capacitance.

HZ/%DUTY CYCLE :
Push this button to select Hz/%duty cycle measuring function
switch is set at Hz/% duty cycle position.
RANGE CONTROL BUTTON:
This is the manual range setting switch.
When power is first switched on, auto-ranging is automatically
selected.
Whenever this switch is pressed, manual range setting is possible.
Pressing the button once switches to the manual ranging mode and
RANGE mark is displayed. Subsequent Button.
When the highest range is reached, the next press returns the
instrument to its lowest range. To cancel manual range, hold the
range hold switch in for more than 1 second and the RANGE mark
disappears and the auto-ranging function is restored (Manual range
except capacitance and frequency)
DATA HOLD BUTTON:
When this button is pushed, the display will show the last reading
and "HOLD" symbol will appear until pushing it again.
Data holding will be canceled automatically when the function switch
is rotated.
RELATIVE ZERO BUTTON:
For convenient readings comparison & offset
FUNCTION / POWER SWITCH:
Switch for changing the measurement function and power on and off.
INPUT JACKS:
This meter has four input jacks that are protected against overload to
the limits except 20A. During use, connect the black test lead to the
COM jack and the red test lead as shown below:

MEASURING VOLTAGE
1. Connect the black test lead to the (-) jack COM and red lead to
the (+) jack (V).
2. Set the function at DCV / ACV range to be used and connect test
leads connects test leads across the source or load under
measurement.
3. Read LCD display. The polarity of red connection will be indicated
when making a DC measurement.
MEASURING CURRENT
1. Connect the black test lead to the (-) jack COM and red lead to
the (+) jack (uA, mA) for a maximum of 400mA. For a maximum of
10A,move the red lead to the (+) jack (A).
2. Set the function switch at uA, mA or A range to be used and push
DC/AC button to select DCA or ACA measuring mode.
