DUTY button again.
Read the value on the screen in %
•
Set the function button to Hz threshold.
•
Connect the black wire to the „COM"
•
connector, and the red to the „Hz" connector.
Connect the device to the circuit and read the
•
frequency value from the display.
Note: When measuring low signals it is advised to use shielded
cables for precise values.
Temperature measuring
Set the function button to ºC position!
•
Connect the type K probe to the device, the
•
red connector to the ºC connector, and the
black to the „COM" connector.
Make the probe touch the subject or place it in
•
the measured environment.
Read the temperature value from the screen.
•
WARNING: To avoid electric shock the probe should not be
placed into electric environment or used in a microwave$
Current measuring
Measurement thresholds: 600µA, 6000µA,
60mA, 600mA, 6A, 10A.
Turn off the power source for the measured
•
circuit. Discharge all high-capacity capacitors.
Set the function button to µA, mA or A mode.
•
Press the „SELECT" button to select the DCA or
•
ACA measuring mode.
Connect the black wire to the „COM" connector
•
and the red to the mA terminal for 600mA
maximal threshold, or to A for 10A maximal
threshold.
Connect the device to the circuit (serial)
•
Read the displayed value from the screen.
•
When measuring DC, the polarity of the red
cable is also displayed (negative only)
If „OL" is displayed and the device is constantly
•
beeping, switch to a higher measuring
threshold.
WARNING: To avoid damage to the device always check
the state of the fuse before measuring! Always use the
specified connectors!
PC Link
The device has a data connector, which enables
it to connect to a computer's serial port. Thus
the measured data is available for processing
(save, analyze, print, etc.) on the computer.
Before connecting the supplied PC-Link soft-
ware needs to be installed on the computer.
Press and hold the Hz/DUTY button and turn
•
on the device, this gets you into PC-Link mode.
The PC-LINK icon will be lit on the screen,
and the serial data transmission mode will be
active.
