2.2 Keypad
A large membrane keypad with tactile feedback makes the instrument easy to use. Each
button, when pressed, has a corresponding graphic indicator on the LCD (Figure 1). Some
buttons have several functions depending on its mode of operation.
Key Function
ON/OFF Powers on and shuts off the meter. The meter will start in pH measurement mode.
HOLD Freezes the measured reading. To activate, press HOLD while in measurement
mode. To release, press HOLD again.
MODE Selects the measurement parameter. Default is pH measurement. Press MODE to
toggle between pH, Temperature, Rel mV (only pH 100), mV, & back to pH
measurement mode.
CAL/MEAS Toggles between Calibration and Measurement mode.
1. If you are in pH measurement mode, press CAL/MEAS to enter pH calibration
mode.
2. If you are in temperature measurement mode, press CAL/MEAS to enter
temperature calibration mode.
3. If you are in Rel mV (only in pH 100) measurement mode, press CAL/MEAS to
enter Rel mV measurement calibration mode.
While in SETup (only in pH 100) menu, pressing CAL/MEAS takes you out and into
the measurement mode.
CON CONfirm function: Press to confirm values in Calibration mode and to confirm
selections in SETup mode.
! ! ! ! / " " " " In Calibration mode:
1. If you are in pH calibration mode, press ! ! ! ! or " " " " key scrolls up or down the
buffer calibration values.
2. If you are in temperature calibration mode, press ! ! ! ! or " " " " key to adjust
temperature values in °C.
3. If you are in Rel mV (only in pH 100) calibration mode, press ! ! ! ! or " " " " key to
adjust mV values.
In SETUP mode (only in pH 100):
Press ! ! ! ! or " " " " key to scroll through options in each SETup programs.
MI / MR (only
in pH 100)
In measurement mode (pH, Rel mV or mV) press MI (memory input) to store values
with its corresponding temperature values in the memory. Press MR (memory recall)
to retrieve data from memory.
(only in pH
100)
Allows you to print current measurement to either the printer or the computer.
SETUP (only
in pH 100)
Takes you into the SETUP mode. This mode lets you customize meter preference
and defaults, view calibration, electrode offset data, clear memory, change pH
resolution, and communication protocol setting.
