Note:
•
If you do not connect a unit to the connectors (or there is a
break) the display will show „OL”.
•
During the test 1 mA current goes through the diode.
•
The display shows the opening voltage of the diode in mV,
and overload if the diode is connected with the polarity
reversed
Temperature measuring
•
Set the function switch to °C position.
•
Connect the black wire of the temperature
measuring sensor to the „mA” connector and the
red one to the „V/Ω/Hz” connector. Put the sensor
to the place measured. The display shows the
measured value in °C.
Note:
•
The device functions with a special temperature measuring
sensor.
•
If the sensor is not connected to the connector, the device
displays the temperature of the environment.
•
Do not connect outward voltages to the connectors, if the
device is in temperature measuring function.
Transistor hFE test
•
Set the function switch to hFE position.
•
Determine if the transistor is NPN or PNP and
place it in the proper connector.
•
The amplification factor of the transistor is
displayed on the screen.
•
IB = 10 μA, VCE = 2,8 V
Frequency measuring
•
Connect the measuring wire or the shielded
cable to the „COM” and „V/Ω/Hz” connectors.
•
Set the function switch to „Hz” position and
touch the wires to the signal source.
Note:
•
Do not measure frequency at a voltage exceeding 250
V(RMs).
•
In noisy environment it is advised to use a shielded cable
for measuring small values.
•
Avoid touching the circuit when measuring high voltage!
•
Frequency measuring changes range automatically.
Inductance measuring
•
Set the function swith to the desired
measuring range.
•
Connect the measured inductor to the LX
connector.
Bemerkung:
•
If the measured inductance is not known, start measuring
at 2 mH range until overload signal turns off.
•
Inductors with low inductance function as short circuits. If
possible, do not connect such inductors to the connectors.
Measuring maximum value
•
Press PK HOLD button once and the highest value
measured will be displayed.
•
Press PK HOLD button once more to turn off the function.
W
arning
•
When measuring voltage make sure that the wires are
not connected to a current measuring connector and
that the function switch is not in resistance or diode
measuring measuring mode. Always check if you have
connected the wires into the proper connectors.
•
Be careful when measuring voltage above 50 V,
especially with high voltage equipment.
•
Avoid connecting to „live” circuits.
•
Turn off the power in the circuit before connecting the
multimeter to measure current and do not measure
above 20 A.
•
Before measuring resistance and diode make sure the
circuit is not under power.
•
Always set the function and measuring range
appropriate for the measuring. If in doubt, set the
maximum measuring range and go backwards.
•
Make sure that the wire and its isolation is not damaged.
•
Only replace fuses to the same type and value.
•
When replacing the fuse or battery make sure all
external power sources are turned off and that the
multimeter is turned off as well.
