10.1. POWERING THE CONTROLLER
Measure is the normal operating mode of the controller. Depending on the probe wired, and the
location of the probe, the display will show measured values with appropriate measurement units.
At start-up, while the controller performs internal checks, the display will show the Hanna Instruments
logo, controller name, date, and firmware version.
In Measure mode, with the probe connected, the controller detects the probe and the probe type.
With no probe connected or a new probe connected, at start-up the controller can display one of the
warning messages detailed below.
