3. Press the ▲ / ▼ keys to highlight pH, ISE (ion concentration), mV (raw millivolts), RmV
(relative millivolts) or ORP (oxidation-reduction potential) as the measurement mode for
channel 1 and press the f2 (accept) key. The meter will request information based on the
selected measurement mode. If channel 1 will not be used, press the f3 (no) key to skip to
the next EZ Startup menu.
a. ISE only: Press the ▲ / ▼ keys to highlight the displayed ISE units as ppm (parts per
million), mg/L (milligrams per liter, % (percent), M (moles per liter) or unitless (no units)
and press the f2 (accept) key.
b. ISE, RmV and mV only: Press the ▲ / ▼ keys to highlight the electrode ID and press
the f2 (accept) key. The electrode ID can be set as pH, ORP, fluoride (F-), ammonia
(NH
3
), ammonium (NH
4
+), nitrate (NO
3
-), nitrite (NO
2
-), sulfide (S
-2
), chloride (Cl-),
chlorine (Cl
2
), bromide (Br-), iodide (I-), cyanide (CN-), sodium (Na+), potassium (K+),
calcium (Ca
+2
), silver (Ag+), copper (Cu+2), lead (Pb+2), cadmium (Cd+2), perchlorate
(ClO4-), fluoroborate (BF
4
-), thiocyanate (SCN-), nitrogen oxide (NO
X
), carbon dioxide
(CO
2
), oxygen (O
2
), monovalent cation (X+), divalent cation (X
+2
), monovalent anion (X-
) or divalent anion (X
-2
). Some of the electrode ID options may not be accessible,
depending on the measurement mode that was selected for the channel.
c. Press the f2 (yes) key to enter an electrode serial number or press the f3 (no) key to
skip this step. To enter an electrode serial number, use the alphanumeric keypad to
enter letters and/or numbers. The meter will automatically advance to the next digit
when no keys are pressed for three seconds. Press the f3 (clear) key to delete any of
the digits. Once the serial number is entered, press the f2 (accept) key. Refer to the
meter pullout guide for the location of the letter keys on the numeric keypad.
d. pH and ISE only: Press the ▲ / ▼ keys to highlight the measurement resolution and
press the f2 (accept) key to save the setting.
e. To change the displayed temperature unit to degree Celsius (°C) or degree Fahrenheit
(°F), press the ▲ / ▼ keys to highlight Temperature Unit and press the f2 (accept)
key. Press the ▲ / ▼ keys to highlight the desired temperature units and press the
f2 (accept) key.
f. Press the ▲ / ▼ keys to highlight ATC1, ATC2 or Manual as the source of the
temperature compensation that will be used for measurements and press the
f2 (accept) key to save the setting. Automatic temperature compensation can be
performed by connecting an ATC probe to ATC input 1 (ATC1) or ATC input 2 (ATC2)
on the meter. If manual temperature compensation is selected, enter the temperature
using the numeric keypad and the decimal key. Once the temperature value has been
entered, press the f2 (accept) key.
g. Press the ▲ / ▼ keys to highlight Auto-Read, On Ready, At Time Intervals,
Continuous, Value Change In Measurement or Timed Reading as the read type and
press the f2 (accept) key to save the setting.

Meter Setup
i. Auto-Read – The meter will display the measurement as it stabilizes and lock and
hold the measurement when it is stable. Once a measurement is locked, press the
measure key to take a new measurement. Once the measurement is locked, the
meter will automatically export the measurement to the data log, if the data log is
enabled in the setup menu, and to a printer or computer, if a printer or computer is
connected to the meter and enabled in the setup menu.
ii. On Ready – The meter will show stabilizing on the display until the measurement is
stable. When the measurement is stable, the meter will show ready on the display.
The display will automatically update if the measurement changes and the
measurement will not lock. Once ready is shown on the display, the meter will
automatically export the measurement to the data log, if the data log is enabled in
the setup menu, and to a printer or computer, if a printer or computer is connected
to the meter and enabled in the setup menu.
iii. At Time Intervals – The meter will read and display a measurement at the set time
interval that is programmed by the operator. At the set time interval, the meter will
automatically export the measurement to the data log, if the data log is enabled in
the setup menu, and to a printer or computer, if a printer or computer is connected
to the meter and enabled in the setup menu. If At Time Intervals is selected, enter
the time interval value in a hours : minutes : seconds format using the numeric
keypad and press the f2 (accept) key.
iv. Continuous – The meter will continuously measure and update the display. No
indicator will be shown on the display. This read type is useful when performing an
experiment that requires continuous measurements to be taken, regardless of the
measurement stability. Press the log/print key to export the measurement to the
data log, if the data log is enabled in the setup menu, and to a printer or computer, if
a printer or computer is connected to the meter and enabled in the setup menu.
v. Value Change In Measurement – The meter will display the measurement when the
reading reaches or exceeds the set high or low value that is programmed by the
operator. When the reading reaches or exceeds the set high or low value, the meter
will automatically export the measurement to the data log, if the data log is enabled
in the setup menu, and to a printer or computer, if a printer or computer is
connected to the meter and enabled in the setup menu. If Value Change In
Measurement is selected, press the ▲ / ▼ keys to highlight Min Value, enter the
minimum measurement value using the numeric keypad and the decimal key, press
the ▲ / ▼ keys to highlight Max Value, enter the maximum measurement value
using the numeric keypad and the decimal key and press the f3 (next) key.
vi. Timed Reading – The meter will display a measurement after a set time delay and
lock and hold the measurement after the time delay is reached. To start another
time delay cycle, press the measure key. Once the measurement is locked, the
meter will automatically export the measurement to the data log, if the data log is
enabled in the setup menu, and to a printer or computer, if a printer or computer is
