Base Option 1
Base Option 1 provides one or two factory fitted outputs. A relay designated as Output 4 is
fitted on all models, and an optional linear mA/V DC designated as Output 6. Base options
cannot be added after manufacture. The functions of outputs 4 & 6 are set in the Output
Configuration sub-menu. Connect as illustrated below.
Base Option 1 Relay Output 4
Present on all instruments, Output 4 is a SPST relay, rated at 2 amps at 240 VAC resistive. If
it is used to switch mains voltages, the supply should be separate from the instrument supply
and should be correctly switched and fused.
