Auto Read is enabled. When fl ashing, the instrument has detected a ‘Stable’
reading and locked the value. Press MEAS to resume live reading. To disable
this feature go to SETUP…SYSTEM…AUTO READ.
Based on the stability criteria settings in System Setup, the instrument has
detected a stable reading.
Password Protection: Enabled.
Requires password for all calibration and setup menus.
Password Protection: Disabled.
No password required for any menu.
Print Setting Timed interval is active; data is being output at regular intervals.
“High Alarm”, “Low Alarm”, or “Cal Due” alarm limit had been reached.
High/Low alarms also have an audible notifi cation.
Sample ID: User selectable fi ve digit number to identify samples.
Measuring Range # of displayed value (1 thru 5). Applicable to Conductivity,
TDS, Salinity, or Resistivity measurements only.
Automatic Temperature Compensation is active; temperature is being actively
acquired with attached electrode. ATC is recommended.
Manual Temperature Compensation is active. A temperature sensor may not
be attached so the default temperature is used.
POWER: Turns the meter on and
off . Upon power on, the meter
automatically begins in the mode
that was last used. Calibration and
memory values are retained even
if meter is unplugged. The time is
displayed during power off .
Up/Down: Use to modify values in
Setup & Calibration modes.
Soft Function Keys (F1, F2,
F3, F4): Function varies.
Operation corresponds to
highlighted tab directly above
in the display.
ENTER: Use to accept selection
or con rm value. In Setup mode,
con rms selection of modi ed
values. In Calibration mode,
con rms calibration values.
Left/Right: Navigates available
Tabs in Measurement mode. Moves
cursor during certain setup modes.

Concentration (ppm, mg/L) Dissolved Oxygen Calibration
1. Press
MODE
for concentration mode & rinse the probe – do not dry.
2. Dip the probe into sample of known DO concentration (i.e. determined by titration or another
instrument). Press
CAL
.
3. Use up/down arrows to adjust the upper DO reading value to match your standard. The lower
reading is the factory default value.
4. Press
after ‘Stable’ appears to accept the calibration.
n
100 % or 0 % Dissolved Oxygen Calibration
1. Press
MODE
for % mode & rine the probe – do not dry.
2. To calibrate 100 %, hold the probe facing downwards in air or dip into air saturated water.
To calibrate 0 %, dip the probe in zero oxygen solution. Press
CAL
.
3. Press
after ‘Stable’ appears to accept the calibration. Allow enough time –
0 % calibration can often take several minutes.
Tip: When calibrating both 100 % and 0 %, always perform 100 % fi rst.
