*Note: When measuring a 3-phase system, special attention should be taken to the
phase to phase voltage which is significantly higher than the phase to earth voltage. To
avoid exceeding the voltage rating of the protection fuse(s) accidentally, always
consider the phase to phase voltage as the working voltage for the protection fuse(s).
RS232C PC computer interface capabilities
The instrument equips with an optical isolated interface port at the meter back for data
communication. Optional purchase PC interface kit BR81X or BR51X (BC81X RS232C
optical adapter cable + BS8151X RS232C software floppies) is required to connect the
meter to the PC computer. The BS8151X RS232C Data Recording System software
equips with a digital meter, an analog meter, a comparator meter, and a Data Graphical
recorder. Refer to the README file in the interface kit for further details.
