The built-in buzzer will
buzz if resistance is
lower than 30
Overload protection: 250 V DC and AC peak value
For continuity test: When resistance is between 30
buzzer may buzz or not. When resistance is higher than 70 , the buzzer
will not buzz.
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.

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
To prevent damage and injuries, install only spare fuses with the ampere
levels, voltage and interruption specified.
