7. Turn off the power of the measured circuit and discharge all the high-voltage capacitors. Remove the test
leads and recover the measured circuit.
 Software
The multimeter has a serial data output function. The optical output can be connected to a USB port on your PC
so the measured data can be recorded, analyzed, processed and printed. Install the software first by inserting the
included CD-ROM into the drive. Install both the software and the USB files. Follow the installation procedure.
 Hold Hz/DUTY pressed while switching on the meter. The PC-LINK symbol is displayed (remember to only
activate the function starting from a switched-off meter, so first switch off the meter prior to enabling the
function).
 Next, insert the optical plug into the multimeter and connect the USB plug with a free USB port.
 Launch the PC-LINK software and click the SET menu and SYSTEM SET.
 Select the proper COM port in the SERIAL PORT SELECT menu:
o Right click My Computer on your computer's desktop and click Properties
o Click the Hardware tab and click Device Manager
o Scroll through the list and select COM x (x being the port number)
 Select the default or a desired sampling rate.
 Press START in the software to measure and view the data.
 Switch off the multimeter first to deactivate the function.
Use the help function in the software for more information.

5. Cleaning and Maintenance

 Set the rotary switch to the OFF position.
 Disconnect all test leads and/or any connectors from the terminals.
 Open the battery compartment using an appropriate screwdriver.
 Remove the fuse by sliding it out of its bracket.
