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 ), ammonium (NH
3
), bromide (Br - ), iodide (I - ), cyanide (CN - ), sodium (Na + ), potassium (K + ),
chlorine (Cl

), silver (Ag + ), copper (Cu+2), lead (Pb+2), cadmium (Cd+2), perchlorate
calcium (Ca
+2
(ClO4 - ), fluoroborate (BF
), monovalent cation (X + ), divalent cation (X
(CO ), oxygen (O
2 2
) or divalent anion (X
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.
