Hach-Lange POLYMETRON 9526 - Manual (Page 15)

Disassemble the connector by unscrewing the two ends of the connector (Nos. 1 and 6 in Figure 4 )
from the main body. Pass the power cable through the connector components numbers 6 through to
2. Then connect the power cable to the female contact (No. 1 in
Figure 4 ).
Reassemble the connector and power the instrument according to the specifications on the product
label (No. 9 in
Figure 1 on page 8). Connect the power cable connector to the instrument power
supply socket (No. 6 in Figure 1 on page 8) after first unscrewing the socket protection cap.
Analog outputs
The analog output is used to record the measurements provided by the instrument (conductivity or
temperature). It is recommended to use a standard cable (reference 08319=A=0005) that can be
purchased through your local Hach Lange representative. This cable should be wired as follows:
• White: pin 1+
• Red: pin 1-
• Blue: pin 2+
• Black: pin 2-
• Orange: do not use
Connect to the 4-20 mA outputs socket (No. 4 in Figure 1 on page 8) after first unscrewing the socket
protection cap.
Electrical conductivity calibration connection
Electrical calibration is used to eliminate any electronic error of the system being tested, in
accordance with standard ASTM D 5391. The conductivity calibration socket connector (No. 5 in
Figure 1 on page 8) is connected to a certified precision resistor (200 kΩ) in order to simulate the
resistivity of ultra pure water.
Only systems using the Polymetron sensor models 8310, 8314 and 8315 have a cable and connector
able to achieve this type of calibration. In this case, simply disconnect the cable from the sensor and
connect it to the instrument conductivity calibration socket after first unscrewing the socket protection
cap. Then follow the instructions in the user manual of the system being tested to perform an
electronic calibration with a value of 200 kΩ.
Install a Secure Digital (SD) memory card
For instructions on how to install an SD card in the controller, refer to Figure 5 . Information on how to
use the SD memory card can be found in Using the secure digital memory (SD) card on page 19.
To remove an SD card, push down on the edge of the card and release, then pull the card up and out
of the slot. After the card is removed, close the slot cover and tighten the cover screws.
