1

3 1/2-Digit Display- The 3 1/2-digit liquid crystal display (LCD)

provides direct readout of oxygen concentrations in the range of

 

0-100%. It also displays "CAL" when the calibration mode is

 

entered.

2

"%" Sign- The "%" sign is present during normal operation

 

when the keypad settings are locked. When the keypad settings

 

are unlocked, the "%" sign is not visible. In the calibration mode,

 

the "%" sign flashes every second.

3

Low Battery Indicator- The low battery indicator appears on

the LCD display when the power supply voltage drops below

 

 

acceptable limits. When the "LOW BAT" icon is visible, batteries

B

should be replaced immediately.

4

ON/OFF Key- (after Calibration) This key is used to turn

the instrument on or off. When batteries are installed in

 

the unit and the unit is in the power off mode, the display

 

will be blank. When the ON/OFF key is pressed once, the unit will

 

start to display the oxygen concentration and the keypad is

 

activated. If the ON/OFF key is pressed again, the unit reverts to

 

the power off mode.

5

LOCK/UNLOCK Key- The presence of the "%" sign on the LCD

 

readout is an indication that the unit is in its normal

 

"LOCKED" state. The unit must be unlocked in order to

 

be calibrated. Pressing the LOCK key will unlock the keypad and

 

cause the "%" sign to disappear. The unit can then be calibrated

 

if desired. If no other keys are pressed within 10 seconds, the

 

"%" sign will reappear and the unit will revert to the "LOCKED"

 

mode.

6

CALIBRATE Key- The Unit will force you to Calibrate the

 

first time power is applied or the sensor is changed. This is

indicated on the LCD by the word “CAL”. Pressing the CALIBRATE key will allow the and arrow keys to calibrate the unit. Also when the keypad is unlocked, the CALIBRATE key is used in conjunction with the and arrow keys to calibrate the unit. When the CALIBRATE key is pressed, "CAL" appears on the LCD readout for 1 second and then the measured calibration concentration is displayed. The calibration value can then be
