On the display read the indication of value and polarity of the measured
resistance of the conductor.
Upon completion the work, set the rotary switch in the "OFF" position.
ATTENTION! If the measured resistance is found in the circuit, before the
measurements turn the power off and discharge all the containers in the circuit.
Notes.
– If the measured resistance value is greater than the maximum value of the
selected measure limit, the display will show the digit "1" in the higher order.
– If the input is not connected, i.e. the circuit is open, the display will show
the digit "1".
– When measuring the resistance in the range up to 200 MOhm, you need
to subtract 1 MOhm from the value of measurement results shown on the display.
– Idling voltage, approximately 2.8 V.
Temperature measurement (only for M838 model)
Set the range selector to "TEMP" position, and the indicator will show the
ambient temperature.
Connect the "K" type thermocouple type to "COM" and "V Ω mA" jacks.
Attach the thermocouple to the measuring object and read on the display the
temperature in degrees Celsius.
Upon completion the work, set the rotary switch in the "OFF" position.
ATTENTION! To avoid electrical shock while changing the function and
works range, make sure that the thermocouple connector is removed from the
device.
Check of circuit continuity (sound continuity test)
Insert the connector of black test probe in "COM" jack and insert the
connector of red test the probe into "V W mA" jack.
Set the rotary switch to " " position.
Connect the test probes to two points of the circuit to be measured. If the
resistance is less than 50 Ohm, you hear a sound signal.
Upon completion the work, set the rotary switch in the "OFF" position.
Diode check
Insert the connector of black test probe in "COM" jack and insert the
connector of red test the probe into "V
W
mA" jack. The polarity of the red probe
is considered positive.
