Before using the instrument, make sure it functions properly by measuring a
known voltage, and check continuity by short-circuiting both test leads.
Do not use the instrument in an explosive atmosphere or in the presence of
Do not use the instrument on electrical networks with a rated voltage or
category higher than those listed for the instrument.
Respect the maximum rated voltages and currents between terminals and in
relation to ground/earth.
Do not use the instrument if it appears damaged, incomplete, or incorrectly
closed.
Before each use, check the condition of the insulation of the leads, the

2.1
The instrument requires a few simple setup steps before use. This includes:
Install the batteries and perform a battery check.
Perform a quick instrument check.
2.1.1
The instrument uses two AA batteries. To install the batteries:
1. Ensure all leads are disconnected from the instrument and the circuit.
2. Remove the protective rubber shock-proof housing from the instrument.
3. Using a screwdriver, remove the two battery cover screws on the back.
4. Lift the instrument stand, and then gently pull on the stand to separate
the battery cover from the instrument.
5. Place the batteries in the casing. Be sure to position each with the
correct polarity.
6. Replace the battery cover, screws, and protective housing.
7. Turn ON the instrument by selecting any dial setting and check that it
powers up correctly. Then check the LCD to see whether or not the Low
Battery indicator is displayed. If so, replace the batteries.

2.1.1.1
To extend battery life, the instrument includes a Sleep mode feature.
In Sleep mode, the LCD turns OFF after 30 minutes of inactivity. Pressing the
(yellow button) restores the LCD. When Sleep mode is enabled, the
P
symbol appears.
To disable the Sleep mode feature, press and hold down while turning the
instrument ON. (Sleep mode will be re-enabled the next time you turn the instru-
ment ON.)
2.1.2
The instrument includes a pull-out stand. When this stand is extended,
the instrument can be placed on a horizontal surface for viewing in an upright
position.
Figure 3-2
On the back of the instrument is a slot that can be slid over a
screw head or other mounting point. This lets you mount the instrument to a wall
or other permanent location.
The removable protective housing includes a set of molded-
a magnetic surface.

ensure it is working properly. We also recommend performing this procedure
whenever you operate the instrument after a prolonged period of inactivity (a
week or longer).
1. Ensure all leads are disconnected from the instrument and the circuit.
2. Turn the instrument ON. Check the startup screen to ensure all symbols
and indicators display. (Due to the short duration the startup screen
appears, you may need to turn the instrument ON and OFF more than
once to check every part of the screen.
3. Turn the rotary dial to the Continuity setting. The LCD should
display the symbol , indicating an overload condition.
4. With the dial still on , insert the red test lead into the +(voltage)
terminal and the black test lead into the terminal. Touch the leads

5. Turn the dial to a voltage setting (for example ), select AC or DC
by pressing , and touch the leads to a known voltage (such as a
battery or AC electrical outlet) to ensure the reading is accurate.

The instrument includes several features that enhance its measurement and
display capabilities, including:

2.2.1
The instrument features both manual range and Auto Range options. Auto Range
enables the instrument to automatically select the best measurement range for
the detected resistance, voltage, current, or capacitance input. This allows you to
have the best resolution without manually resetting the range.
By default, the instrument starts in Auto Range mode, as indicated by the
indicator on the LCD. To enable manual ranging, press the button. Each
subsequent press of this button increases the measurement range by one order
of magnitude (10x). When the highest range is reached, pressing this button
returns to the lowest range.
To exit manual ranging, press and hold down the button until is
displayed on the LCD.
2.2.2
To freeze a measurement displayed on the LCD, press the button once.
The measurement will remain on the screen until you press the button
a second time to resume normal measurement display. When display hold is
enabled, the symbol appears on the LCD.
By default, the instrument displays measurements continuously in real-time. You
can instead have the instrument display only the minimum and maximum values
of a measurement session. To do this, turn the instrument dial to the desired
measurement type, and proceed as follows:
1. Press the button. This initiates Max-Min mode, with the
maximum value displayed for the measurement session. (The
symbol appears.) This value will remain on the screen until a higher
value is measured.
2. Press the button a second time to view the minimum value
measured during this session. (The MIN symbol appears.) As with the
maximum, the minimum value remains on the LCD until a lower value is
measured.
3. Press the
obtained by subtracting the maximum from the minimum. (The
symbol appears.)
4. To exit this mode, press and hold down the button for longer
than 2 seconds.
