To turn on the MiniRAE Plus Professional PID Unit, press
[on] key. The audio buzzer will beep once and the display will
show "HG- x.xx" or "Su- x.xx" to indicate the operating mode

ensure that they are functional. The sampling pump will be
turned on and start to draw air sample.
After about 30 seconds, the display will change to instantaneous

diagnostics tests. If there is any problem with the unit, an error
message will be displayed (Refer to section 9 for
troubleshooting of the particular error condition).
