1 INTRODUCTION
Thank you for purchasing this pH, ORP, or Conductivity Field Monitor.
The Field Monitor Series feature microprocessor technology, which gives it many
reliable, user-friendly features. These monitors were designed for long-term low-
maintenance use. Just plug in the AC adapter, calibrate and the unit is ready for
continuous monitoring. No batteries required.
2 FRONT PANEL
The front panel consists of a 3-digit LED display, 2 keys for the pH Monitor, 4 keys for
the ORP Monitor, and 3 keys for the Conductivity Monitor.
2.1 Keys for pH Monitor
CAL The CAL key switches monitor into calibration mode
from measurement mode. In calibration mode CAL
switches monitor back to measurement mode. See
page 3 for details.
ENTER Press the ENTER key to confirm the calibration while
in calibration mode.
2.2 Keys for ORP Monitor
CAL The CAL key switches monitor into calibration mode
from measurement mode. In calibration mode CAL
switches monitor back to measurement mode. See
page 5 for details.
ENTER Press the ENTER key to confirm the calibration while
in calibration mode.
S The S Up/Increment key scrolls value up in
calibration mode.
T The T Down/Decrement key scrolls value down in
calibration mode.
2.3 Keys for Conductivity Monitor
CAL The CAL key switches monitor into calibration mode
from measurement mode. In the calibration mode,
pushing CAL key confirms the calibration value and
returns to measurement mode. See page 7 for details.
S The S Up/Increment key scrolls value up in
calibration mode.
T The T Down/Decrement key scrolls value down in
calibration mode.
Pressing
S and T together while in calibration mode
switches the monitor back to measurement mode from calibration mode.
