2.0 SPECIFICATIONS  
 
 
 
 
 
 
 
 
DISPLAY:  
  3 1/2 digit LED, 1/2" high digits 
 
 
 
 
 
MEASURING RANGES:   
  D.O.: 0-20.00 ppm and 0-100% saturation, switch 
 selectable 
  Temperature: 0-40°C (32 to 104°F) 
 
POWER REQUIREMENTS:   
  98-132 Vac, 50/60 Hz (less than 10 VA) 
 
  Optional:  196-264 Vac, 50/60 Hz 
 
AMBIENT CONDITIONS:   
  -30 to 50°C (-22 to 122°F)   
  0 to 90% R.H. non-condensing 
 
 
 
ANALOG OUTPUTS: 
  Non-isolated 0-1 mA, 100 ohms maximum load 
  Non-isolated 0-5 Vdc, 1000 ohms minimum load 
  Isolated 4-20 mA, 800 ohms maximum load 
The isolated output is isolated from the input, ground 
line power and all other outputs 
Range Expand: The 4-20 mA analog output can be 
made to represent any segment of the measuring 
scale.  Minimum segment is 10% of full scale. 
Output Hold: The analog outputs are automatically 
placed on hold during calibration or other setup 
operations. 
Temperature Output: The 0-5 Vdc output can be 
programmed to follow either the process temperature 
or dissolved oxygen. 
 
TEMPERATURE COMPENSATION: 
 
Automatic 0 to 100°C (32 to 212°F) 
 
ALTITUDE COMPENSATION: 
Automatic 0 to 40°C (32 to 104°F) 
 
DIAGNOSTICS: 
When system error is indicated, call STATUS to obtain 
condition code.  On-board simulated input to aid in 
troubleshooting to obtain condition code. 
 
MEMBRANE ALARM: 
A relay activates if membrane is perforated. 
 
TEST: 
  Display value and analog outputs can be set manually 
to any value for testing and diagnostic purposes.  This 
feature allows the outputs to be tested independently 
of process value. 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
SAFETY & SECURITY:
   
Non-volatile memory (EEPROM) 
Passcode protected if selected 
Watch-dog timer monitors microprocessor 
Instrument automatically returns to on-line operation if 
accidentally left in menu mode 
(This feature may be held disabled if desired)

RESPONSE TIME: 20 seconds to 90% of value upon 
step change at 20°C 
 
 
 
 
ENCLOSURE:  NEMA 4X fiberglass reinforced polyester 
enclosure with four 1/2” conduit holes and mounting 
feet for surface mount
