Pressure Probe.
When using the Pitot Probe, turn this button and allow it to spring out;

the button in and turn to lock it in position. In this position the switch
button slot must be vertical (aligned with arrows on label) for proper
instrument operation.

The plug-in port (D) accepts the various probes and allows you to rotate
them 360. (+) and (–) ports (E) are for hose connections to the meter.
Your set will include two Range Selectors that are identified by red or
black lettering. This color coding relates to the same colored scales on
the meter.
