PORTABLE TESTER 

The PORTA-PROBE

TM

 

The PORTA-PROBE

TM

 II (Figure ) is a battery-operated digital 

portable tester/signal generator.  It is designed to test the ORP, 
pH,  conductivity  and  temperature  sensors  and  to  generate 
calibrated signals to test the controller.  It is supplied with a 9V 
battery and a pair of shielded cables with BNC connectors. 

The PORTA-PROBE

TM

 II is not used to calibrate the ORP and 

pH sensors.  This should be done with a chemical test kit, such 
as DPD for Free Chlorine and Phenol Red for pH. 

ORP and pH Simulation 

Set the Mode Switch to SIMULATOR. 

Use the two coaxial cables to connect the BNC connectors on 
the tester to the respective BNC connectors on the controller.   

Set  the  Selector  Knob  to  either  pH  or  ORP  Simulator.    The 
readings  on  the  controller  should  match  the  readings  of  the 
tester display  (unless offset by calibration of the pH probe). 

The  outputs  of  the  ORP  and  pH  simulators  can  be  adjusted 
with the two small knobs located below the digital display. 

The ORP range is 0 to 1,000 mV. 

As shown in Table III, the pH range is from -180 to + 180 mV 
(10 to 4 on the pH scale). 

These outputs can be used to test for proper operation of the 
feed and alarm features of the controller. 

NOTE  1:  Due  to  signal  stabilization,  the  readings  on 
the controller may take up to 10 seconds to reach full 
value. 

NOTE  2:  ORP  and  pH  signals  can  be  generated 
simultaneously but only one signal is displayed. 

Conductivity Testing 

Connect  the  conductivity  connectors  on  the  portable  tester  to 
the  controller  input  and  perform  the  required  simulation  and 
testing. 

Temperature Testing 

Connect  the temperature  connectors on the portable tester  to 
the  controller  input  and  perform  the  required  simulation  and 
testing.
