Display
The display shows the working condition and current setting
of the 3200P pH Meter. After the power supply is connected,
press [On/Off] to turn on the meter. After a successful power
up, the meter model, version number, and other information
displays. After the system self- check, the meter goes to the
initial state as shown in Figure 7. The left side of the screen
shows current system time and the right side shows the
current measuring mode, parameters, and the last calibration
data.
Keypad
The meter has 15 operating keys. The keys are shown in
Figure 8 on page 20 and described in Table 1 on page 20.
Most keys have two values, a numeric entry and a function.
Which one applies depends on the display; if it is waiting for
a number, the numeric entry applies, otherwise, the function
applies. To complete a numeric entry, press [Enter].
