TEMPERATURE
•
Set the rotary switch to the measurement function “mV °C °F” then press the
SELECT
button to choose between celsius (°C) or fahrenheit (°F).
•
Insert the temperature connector into four terminals and connect two temperature
probes to the temperature connector.
•
The probes detect the surface of the object under test as shown below right.
•
Directly read the temperature values on the two surfaces under test on the display.
•
Press the function button
MENU
to open one menu option and then press
F2
in which basic temperature measurements can be modified to enter the relative
measuring mode.
•
Press
F4
to close the window of additional functions and use the cursor buttons to
select menu options.
•
The red cursor indicates the selected item.
Warnings
•
The ambient temperature for the
meter must not exceed the range
from 18°C to 28°C, otherwise it will
cause measurement errors. The
measurement effects are more
obvious at low temperatures.
•
Remove the temperature probes after
completing all of the measurement
operations.
LPF MEASUREMENT
•
Insert the red test lead into the V
terminal and the black test lead into
the COM terminal.
•
Set the rotary switch to
Ṽ
and connect
the test leads to the lower or load to
be tested in parallel as shown right.
•
Press the function button
MENU
to view the menu options. Use the cursor
buttons to select “Low Pass”, then press the
MENU
function button to enter LPF
measuring mode.
•
The meter performs the measurement in AC mode. The AC signals go through a
filter which holds up the voltage higher than 1kHz. As shown right, the low-pass
filter can measure the composite signals of sinusoidal wave generated by inverter
and variable-frequency motor.
Warnings
•
To avoid electric shock or personal injury, do not use the low-pass filter to verify
hazardous voltage, as the voltage over the indicated value may exist.
•
Firstly, measure the voltage by disconnecting the filter to see any hazardous
voltage, then select the filter function.
•
In LPF measuring mode, the meter will turn to manual mode. Press the
RANGE
button to select a range. When the low-pass filter is enabled, the automatic range
is unavailable.
