Operation
5.1 Sensor display
By simultaneously pressing ↓ and ^ you alter between MAC 080 main menu and the sensor
information display for the selected sensor. PAS 2000 has two information pages. The first one
shows in addition to the measured value maximum, minimum and average values for the last
24 hours. The values are based on hour values which means they may jump when a new hour
starts and the oldest is skipped.
The second information display shows the date of the last calibration (PAS 2000 pH only) and the
date the electrode was changed.
5.2 Menu for sensors
Use ↑ or ↓ to select the sensor in the main display. The menu for the selected sensor is accessed
by pressing ^ for five seconds. If the selected sensor is not active (the text No transmitter
No transmitter No transmitter No transmitter is
shown) a warning is displayed that asks you to make another choice in order to show the sensor
menu.
