Page 3: Preliminary Examination
PRELIMINARY EXAMINATION PRELIMINARY EXAMINATION PRELIMINARY EXAMINATION PRELIMINARY EXAMINATION PRELIMINARY EXAMINATION Remove the instrument from the packing material and examine it carefully to make sure that no damage has occurred during shipping. If there is any noticeable damage, notify your Dealer. Note: Save all packing materials until you are sure that the instrument functions correctly. -
Page 4: Mechanical Layouts
The recorder output terminals are isolated from the controller circuitry to avoid any interference and are user-switchable between 0 to 20 mA or 4 to 20 mA. The controller is housed in a rugged, modular, fiber-reinforced ABS housing. All models can be wired to work with 110/115V or 220/240V at 50/ 60 Hz power supplies. - Page 5 Fig. 3 Figure 3 is a dimensioned, bottom view of the wall mounted controller. The modular design isolates the control circuitry from the contacts making it possible to make the connections and then close the compartment. Adjustments can then be made only in the control area, without having to open the contacts compartment.

• Once the controller is calibrated to a solution by referring to its value at 25 °C, all subsequent measurements are temperature compensated to 25 °C. You can also obtain temperature compen- sation to a different temperature reference point by calibrating the meter to that value. -

Page 21: Suggested Installations For Ec/Tds Probes
IMPORTANT: After performing the cleaning procedures rinse the probe thoroughly with distilled or tap water. Dry it and replace the sleeve ensuring that the air-vents are nearer to the cable end and recalibrate the controller. TROUBLESHOOTING If the controller does not respond properly or constantly reads zero or a value close to it, or is in over range, check the probe and cable for cracks. - Page 22 HI 3002 FOR IN-LINE INSTALLATION The drawing illustrates the ideal installation system since the stream pressure in the pipe forces the air bubbles out automatically. HI 3001D illustrated previously can also be ,mounted in this fashion. However the longer stem of HI 3002 facilitates an easier escape route for any air bubbles.
