Connect the probes to the source or load to be
1kΩ
measured.
4)
Read the result from the LCD display.
10kΩ
Note:
•
To measure a resistance above 1MΩ, a stable reading
may take a few seconds to obtain.
•
When the input is not connected, i.e. the circuit is
open, the number "1" will be displayed if the range is
exceeded.
•
When testing a circuit resistance, make sure that the
circuit under test is completely disconnected from
the power supply and that all capacitors have been
completely discharged.
3.3.1.4. DIODE TEST
1)
Connect the black test lead to the "COM" jack and
the red test lead to the "V / CAP, Ω " jack (red wire
polarity: +).
2)
Turn the dial to " ".
3)
Connect the red test lead to the anode (+) and the
black lead to the cathode (-) of the diode being
tested.
4)
Read the voltage drop from the display. If the probes
are connected inversely to the diode, the display will
show "OL".
3.3.1.5. ELECTRICAL CIRCUIT CONTINUITY TEST
1)
Connect the black test lead to the "COM" jack and
the red test lead to the "V / CAP, Ω " jack.
2)
Turn the dial to " ".
3)
Connect the probes to the circuit to be tested. The
0,01μF
acoustic signal will be continuous, and the red LED
0,01μF
will light up if the resistance is less than about 50Ω.

and the red test lead to the "V /CAP, Ω " socket.
2)
Set the knob to the "200uF " position.
3)
Connect the probes to the item being tested.
4)
Read the result from the LCD display.

2)
Set the dial to the selected range "A " or "A ~"
3)
Connect the probes to the source or load to be
measured.
4)
Read the result from the LCD display. The polarity
of the red test lead will be displayed along with the
measured value.
3.3.1.8. HFE TEST
1)
Set the dial to the hFE position.
2)
Determine if the tested transistor is NPN or PNP,
locate the emitter, base and collector leads.
3)
Insert the leads into the proper holes of the hFE
socket on the front panel.
4)
Read the approximate hFE value.
3.3.1.9. BATTERY TEST
1)
Connect the black test lead to the "COM" jack and
the red test lead to the "V / CAP, Ω " jack
2)
Set the dial to the selected 1.5V, 9V or 12V range.
3)
Connect the black test lead to the negative pole
of the capacitor. Connect the red test lead to the
positive pole of the capacitor.
4)
4) Read the result from the LCD display.
3.3.2. DIRECTIONS FOR USE
•
If the indication range is exceeded, the message "OL"
will be displayed
•
When the "
•
When the scale of the value to be measured is
unknown, set the range dial to the highest range
position.
•
A message displayed only as the number "1" or "-1",
means the range has been exceeded and a higher
measurement range should be set with the dial.
•
A displayed triangle with an exclamation mark
means that
»
A voltage higher than 600V can not be applied.
A higher voltage can be shown but it can
destroy the internal circuits of the device or
cause an electric shock.
»
The maximum mA current is 200mA and the
maximum for 10A is 10A. Exceeding these limits
will destroy the fuse. Since the 10A range is not
protected, the measurement time should be
less than 1 second to prevent the circuit from
overheating.
•
Be careful when measuring high voltages because of
the risk of electric shock.
3.4. CLEANING AND MAINTENANCE
a)
Use only non-corrosive cleaners to clean the surface.
b)
After cleaning the device, all parts should be dried
completely before using it again.
c)
Store the unit in a dry, cool place, free from moisture
and direct exposure to sunlight.
d)
Do not spray the device with a water jet or submerge
it in water.
e)
The device must be regularly inspected to check its
technical efficiency and spot any damage.
f)
Use a soft cloth for cleaning.
g)
Do not leave the battery in the device if it will not be
used for a longer period of time.
should
be
discharged
before
h)
Protect the device against moisture. If it is wet, wipe
it dry immediately. Liquids may contain minerals
which can corrode electronic circuits.
i)
Use and store the device in standard temperature
conditions. Extreme temperatures can shorten the
life of the device, damage the batteries and deform
or melt plastic parts.
j)
Handle the device with care. Dropping it may damage
printed circuit boards and cause malfunctioning.
k)
Protect the device from dust and dirt.
l)
Use only new batteries of the size and type indicated
in the technical specifications. Before installing or
replacing the batteries, make sure that the device is
not connected to an external circuit, that the control
knob is set to "OFF", and that the test leads are
disconnected from the terminals.
m)
To avoid electric shock, disconnect the test leads
from the measuring circuits before replacing the
fuse. To prevent fire, replace a blown fuse only with
a fuse whose rating is F-200mA / 250V.
n)
b) Do not use the device until the back cover is
properly closed and secured with a screw.
SAFE REMOVAL OF BATTERIES AND RECHARGEABLE
BATTERIES
