• Start the motor. Read the display reading. Divide the reading between
the number of cylinders. The result is the turn speed. (tachometer).
7. AUTOMATIC SHUT OFF AND TURNING ON THE
LCD LIGHT
• After being turned on, the LCD shows “APO”, meaning the multimeter
in in automatic power off mode. When the multimeter automatically
shuts off, press the “HOLD” button to turn it on.
• Press briefly the “HOLD” button to turn off / turn on the “HOLD”
function. Press the “HOLD” button longer to turn off / turn on the
background light.
8. FUSE AND BATTERY REPLACEMENT
If the sign appears in the display, it means replace battery. Remove
the screws and open the housing in the back. Replace the low battery
and set a new one.
Using automatic recuperation fuses after eliminating the external fault,
returns the fuse to normal and the multimeter can be used normally.
There is no need to replace the fuse.
Range 20 A has a fast fusion 20 A / 250 V fuse.
Replace the fuse according to specifications: 20 A; 250 V; FAST; Min;
Interrupt Rating 20 000 A; diameter 5 mm x 20 mm
Use 1,9 V DC, Carbon-Zinc battery (included).
To prevent false readings which lead to electric shock or personal injuries,
replace the battery as soon as the indicator symbol shows.
To prevent damage and injuries, install only spare fuses with the ampere
levels, voltage and interruption specified.
TO OPEN THE BATTERY COVER
To replace the fuse, remove the screw in the support frame. Remove the
multimeter from the sleeve. Remove the back cover. Replace the fuse with
a new one with the same size. Assemble back the support frame. Reinstall
the screws.
1. If the measured current is unknown beforehand, set the functions
switch in the highest range. Then, switch into the adequate range
according to the value shown.
2. If the LCD shows “OL”, means it is above range. Switch the functions
switch into a higher range.
MEASURING DC CURRENT
• Insert the black test probe into the “COM” connector and the res one
into “mA” connector. (Maximum 200 mA) or insert the red one into the
“20 A” connector (maximum 20 A).
• Set the function switch into the adequate DC current range. Connect
the test probes through the circuit to be measured. The current value
and polarity in the point to which the red probe is connected is shown
in the LCD.
1. If th measured current is unknown beforehand, set the functions switch
in the highest range. Then, switch into the adequate range according to
the value shown.
2. If the LCD shows “OL”, means it is above range. Switch the functions
switch into a higher range.
3. When measuring 20 A. The continuous measurement of high current
may heat the circuit, affect precision and damage the multimeter.
MEASURING AC CURRENT
• Insert the black test probe into the “COM” connector and the red one
into the “mA” connector (maximum 200 mA), or insert the red test
probe into “20 A” connector (maximum 20 A).
• Set the functions switch into the adequate AC current range. Connect
the test probes through the circuit being tested.
1. If the measured current is unknown beforehand, set the functions
switch in the highest range. Then, switch into the adequate range
according to the value shown.
2. If the LCD shows “OL”, means it is above range. Switch the functions
switch into a higher range.
3. Pay attention when measuring 20 A. The continuous measurement of
high current may heat the circuit, affect precision and damage the
multimeter.
MEASURING RESISTANCE
• Insert the black test probe into the “COM” connector and the red one
into “INPUT” connector.
• Set the functions switch into the adequate resistance range. Connect
the test probes through the resistance to be measured.
1. If the resistance value measured exceed the maximum value of the
selected range, the LCD will show “OL”. Therefore, set the functions
switch in a higher range. When resistance is above 1 M Ω, the
multimeter will take a few seconds to stabilize. This is normal for high
resistance readings.
2. When the input terminal is in the open circuit, it shows overload.
3. When measuring resistance in line, double check the power supply is
off and all the capacitors are completely released.
MEASURING CAPACITANCE (automatic range)
• Insert the red test probe into “INPUT” terminal and the black one into
the “COM” connector.
• Set the functions connector into 20 mF range. connect the test probes
to the capacitor being measured. (NOTA: Polarity of the red test probe
is “+”).
1. Before measuring, it is possible the LCD display is not showing zero.
The residual reading gradually decreases. This can be ignored.
2. When reading a very large capacitance, LCD will show some instability
value.
DIODE AND CONTINUITY TEST
• Insert the black test probe into terminal “COM” and the red one into the
“INPUT” connector. (NOTE: Polarity of the red test probe is “+”).
• Set the functions switch into “ ” range. Connect the test probes
into the diode to be measured. The reading is an approximation to the
positive drop of the diode voltage.
• Connect the test probes into two pints in the measured circuit. If the
buzzer rings, resistance is lower than 50 Ω approximately.
MEASUREMENT OF hFE
• Set the range knob in hFE.
• Verify the transistor type is NPN or PNP. Insert the emitter, base and
collector in the adequate connector.
MEASUREMENT OF TEMPERATURE
• Set the functions switch into “ºC / ºF” range.
• Insert the black plug (o “-“) of the type K thermocouple probe into
connector “COM” and the red plug (o “+”) into the “INPUT” connector.
• Carefully, touch with one end of the thermocouple probe the object to
measure.
• Wait one moment: read the display reading.
• Press the “Select “button to select “ºC” or “ºF “ mode. The “ºC” or
“ºF “symbol will show as indicator.
MEASUREMENT OF FREQUENCY AND WORK
• Set the functions switch into the required position of “Hz Duty”.
• Connect the black test probe into “COM” connector and the red one
into “INPUT” connector. (Note: Polarity in the red test probe is
positive “+”).
• Read the display reading.
• Press “Select” button to select “Hz” or “Duty” mode. The “Hz” or
“Duty” symbol will show as an indicator.
Do not apply more than 250 V RMS to input. There is a possibility that the
voltage indication is higher than 100 V RMS, but the reading might be out
of specification.
MEASUREMENT OF THE PERMANENCE ANGLE
• Connect the black test probe into the “COM” connector and the red
rest probe into “INPUT” connector.
• Set the dial into the desired “DWELL” range, in accordance with the
motor cylinders to be measured.
• Connect the black test probe to the iron bars or battery negative pole,
and the red test probe into the distributor terminal in the starting coil.
• Star the motor and set in idle. Read the permanence angle value in the
LCD.
MEASUREMENT OF THE TACHOMETER
• Connect the black test probe into the “COM” connector and the red
test probe into the “INPUT” connector.
• Set the dial into the desired “TACH x 10” range according to the motor
cylinders to measure.
• Connect the black test probe to the iron bars of the battery negative
pole, and the red testing probe into the distributor terminal of the
starting coil.
WARNING!
Disconnect the test probes before opening the batteries back cover.
1. Changing battery and fuse shall only be carried out after the test
probes are disconnected and the device id off.
2. Using the right screwdriver, loosen the screws and remove the lower
part of the housing.
3. The multimeter uses a 9 V DC battery. Remove the tips from the
battery connector from the terminals in. the new battery. Reinsert
the battery in the housing cover. Arrange the new battery tips to
avoid getting jammed in the housing bottom.
