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.

Base Option 2
Base Option 2 provides one or two factory fitted outputs. An optional relay designated as
Output 5, and an optional linear mA/V DC designated as Output 7. Base options cannot be
added after manufacture. The functions of outputs 5 & 7 are set in the Output Configuration
sub-menu. Connect as illustrated below.
Base Option 2 Relay Output 5
Part of base option 2, Output 5 is a SPST relay, rated at 2 amps at 240 VAC resistive. If it is
