1. Program descriptions
Briefly describes the 6 programs
2. Temperature LCD
This LCD displays the temperature measured by the HI7669/2W
probe or the value that was manually set through the keyboard.
If the temperature has been set manually, the "°C" symbol will
flash.
When the temperature probe is connected the measured tempera-
ture is displayed and the "°C" symbol stops flashing.
When the temperature measured by the probe is out of range (-10
to 125°C) the "Err3" signal appears.
3. pH and mV LCD
This LCD displays the pH or mV reading (pH and mV is toggled
with the RANGE key). The corresponding pH or mV symbol will be
displayed along with the measured value.
An error signal ("Err1", "Err2", "Err4" or "Err5") will appear on this
display to indicate that the range is exceeded or that the buffer
used for calibration is not recognized by the meter's microproces-
sor.
