Functions

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 confi rm value. In Setup mode, 

confi rms selection of modifi ed 

values. In Calibration mode, 

confi 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.
