FUNCTIONAL DESCRIPTION HI 8915
1) BNC socket for combination pH or ORP electrodes.
2) LCD display.
3)
HOLD to freeze the reading on the display.
4) mV to display the mV (ORP) readings when using an ORP
electrode or the mV equivalent to the pH values when using
a pH electrode.
5) OFFSET trimmer for OFFSET calibration of pH
6) + recorder output (mV output, positive connection).
7) Phono plug socket for temperature probe HI 7669AW.
8)
ON/OFF to switch the instrument on or off.
9) pH to display the pH value.
10) °C to display the temperature measurement (when the
temperature probe is disconnected, the LCD will show 25°C).
11) SLOPE trimmer for SLOPE calibration of pH.
12) - recorder output (mV output, negative connection).
