 Press the SHIFT button followed by the RANGE button, the meter enter PC-Link

mode. T the symbol “PC-LINK” will appear on the LCD [E] and the serial data

output function is active.

Notes:

 It is not possible to enter PC LINK during measurement; the meter must be

switched off first.

 Run the PC-LINK software, click the SET menu. Select the System Set. Then

select the proper COM port in the Serial Port Select. The COM port is normally

detected automatically. To determine the COM port manually, go to Device

Manager:

 Right-click the My Computer icon on the Windows desktop, and then click

Properties.

 Click the Hardware tab and then click Device Manager.

 Scroll through the list of installed devices and locate the Ports (Com and LPT)

entry. Click the plus (+) next to this entry to view the installed ports, If no

errors occurred, the “Prolific USB-to-Serial COM Port (COM x)” will appear, COM

x is the port, with x = a specific number.

 Select the default sampling rate or set a desired sampling rate.

 Now press the Start in the PC-LINK SOFT to measure and view the real-time data

or graph in the software interface.

 To disable the serial data output function, switch the meter OFF or press the

SHIFT button followed by the RANGE button.

 More information about the PC-LINK SOFT can be found in the help-file of the

software.

7. Operating instructions

Risk of electric shock during operation. Be very careful when

measuring live circuits.

Before measuring, always make sure the meter and/or test probes are not

damaged and verify the connections, selected function and range.

 Never exceed the limit value for protection. This limit value is listed separately in

the specifications for each range of measurement.

 Do not touch unused terminals when the meter is linked to a circuit which is being

tested.

 Only use the meter in the indicated overvoltage/installation category. Never

measure voltages that might exceed the indicated category values.

 When a measuring range is unknown, always select the highest possible range

and lower to the appropriate range.

 Disconnect the test leads from the tested circuit before rotating the range selector

in order to change functions.

 When carrying out measurements on a TV set or switching power circuits, always

remember that high amplitude voltage pulses at the test points might damage the

meter.

 Always be careful when working with voltages above 60Vdc or 30Vac rms. Keep

your fingers behind the probe barriers at all times during measurement.

 Do not measure current in circuits with voltages > 1000V.

 Never perform resistance, diode or continuity measurements on live circuits. Make

sure all capacitors in the circuit are depleted.
