Measuring Temperature
1.
In measuring the temperature, insert the cold end (free end) of thermocouple sensor into
the temperature terminals and at the same time note the polarity. Place the working end
(temperature measuring end) on or inside the object to be tested. You read the temperature
directly from the display which is expressed in ºC or ºF.
Testing Diodes and Continuity
1.
Insert test leads into input terminals (Red to VΩ and black to COM, "+" for the red test
lead). Then set the rotary switch to "
displayed reading is the approximate value of forward voltage drop of diode.
2.
Connect test leads to the circuit under test, if the resistance between two tested ends
is<10Ω, the built-in buzzer sounds.
Auto Power Off
1.
Auto Power Off circuit is set for the instrument. When working time of the instrument is
about 15min, the power is automatically cut off. Then the instrument goes into sleeping
state. In this case, the instrument consumes about 7ɥA current.
2.
If you want to restart the power after power off, press the power switch twice.
This digital universal meter is an electronic precision instrument. Do not change circuits
randomly and note the following aspects:
1.
Do not connect to voltages higher then 600V DC or 600AC RMS.
2.
Do not connect to the voltage source when the function swich is at "current ranges", "Ω" and
"
,
".
3.
Do not use this instrument when the battery is not well connected or its back cover is not
tightly installed.
4.
You can only change the battery or fuse when the test leads are removed and power is cut-off.
