Safety precautions
Safety
DANGER
Engines produce carbon monoxide which
is odorless, causes slower reaction time,
and can lead to serious injury. When the
engine is operating, keep service areas
WELL VENTILATED or attach the vehicle
exhaust system to the shop exhaust
removal system.
Set the parking brake and block the
wheels before testing or repairing the
vehicle. It is especially important to block
the wheels on front-wheel drive vehicles;
the parking brake does not hold the drive
wheels.
Wear an eye shield when testing or
repairing vehicles.
Exceeding the limits of this meter is
dangerous. This will expose you to serious
or possibly fatal injury. Carefully read and
understand the cautions and the
specification limits of this meter.
Voltage between any terminal and ground
must not exceed 600V DC or 600V AC.
Use caution when measuring voltage above 25V DC or 25V AC.
Circuit tested must be protected by a 20A fuse or circuit breaker.
Do not use the meter if it has been damaged.
Do not use the test leads if the insulation is damaged or if metal
is exposed.

Danger
Avoid electrical shock: do not touch the test
leads, tips or the circuit being tested.
Do not try a voltage measurement with the
test leads in the 20A or the mA terminal.
When testing for the presence of voltage or current, make sure
the meter is functioning correctly. Take a reading of a known
voltage or current before accepting a zero reading.
Choose the proper range and function for the measurement. Do
not try voltage or current measurements that may exceed the
ratings marked on the Function/Range switch or terminal.
When measuring current, connect the meter in series with the
load.
Never connect more than one set of test leads to the meter.
Disconnect the live test lead before disconnecting the common
test lead.
The mA and the 20A terminals are protected by fuses. To avoid
possible injury or damage, use only in circuits limited to 400mA
or 20A for 30 seconds.

IMPORTANT
To maintain accuracy of the meter, replace the discharged
battery immediately when the symbol “
BAT
” appears on the
meter display.
Avoid measuring error from outside interference. Keep the
meter away from spark plug or coil wires.
Avoid damaging the meter when testing voltage. Disconnect
the test leads from the test points before changing functions.
Do not exceed the limits shown in the table below:

Ohms can not be measured if voltage is present, ohms
can be measured only in a non-powered circuit. However,
the meter is protected to 600 volts.

Meter Basics
1. Digital LCD display
Display features:
1a. Symbols to identify function
1b. Four character digital display
The digital display is best for
stable inputs. The bar graph is
best for rapidly changing inputs.
2. Function buttons
Press the button to select a
function. A symbol will display to
verify your choice.
3. Rotary Selector Switch
Turn this switch to select a
function or turn the meter OFF.
4. Volts Terminal
The Red test lead is used to
measure; Amps, Volts, Ohms,
TEMP, Hz, RPM, Cap, mS and
Dwell.
The Black test lead is used
in the Common(COM) terminal for
all tests.

Manual Ranging
The meter turns on in the autoranging mode.
Press the Range button to go to manual ranging.
The display icon "
" will appear. Each press of the range
button will step to the next range as indicated by the units and
decimal point location. Press and hold the Range button for two
seconds to return to autoranging.
Data Hold
The Data Hold function allows the
meter to "freeze" a measurement for
later reference.
1. Press the DATA HOLD button to
“freeze” the reading on the indicator.
The indication of “HOLD” will appear
in the display.
2. Press the DATA HOLD button
again to return to normal operation.
Peak Hold
The Peak Hold function captures
the peak AC or DC voltage or current.
The meter can capture negative
or positive peaks as fast as
1 millisecond in duration.
1. Set the function switch to the Amps or Volts.
2. Press and Hold the PEAK button until “CAL” appears
in the display. This procedure will zero the range
selected & the meter will go into manual ranging mode.
3. Press the
PEAK
button,
Pmax
will display.
4. The display will update each time a higher positive
peak occurs.
5. Press the
PEAK
button again,
Pmin
will display. The
display will now update and indicate the lowest
negative peak.
6. To return to normal operation, press and hold the
PEAK
button until the
Pmin
or
Pmax
indicator
switches off.
Note
: If the Function switch position is changed after a
calibration the Peak Hold calibration must be repeated for the
new function selected.
