1. INTRODUCTION
In the modern automatic measurement system, communication
between equipments and computers is essential. The measured
procedures can be varied with user’s testing programs, therefore, the
Digital Multimeter can be operated remotely from an instrument
controller or computer across the RS232 interface (optional) or GPIB
(optional).
Interface selection and setup
Press [SHIFT][SET] in sequence into SET mode, then press [RS-232] or
[GPIB] the white characters with blue background to set the RS232 OR
GPIB interface. If the indicator of negative sine lights, the value
displayed on the front panel is the current setting value. Use [▲][▼] can
adjust the baud rate (or GPIB address). Finally, press [ENTER] to store
the setup or press [SHIFT] to cancel the setup.
