& MAINTENANCE

PREPARATION PROCEDURE

Remove the protective cap.

DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT.

This is normal with electrodes and they will disappear when rinsed

with water.

During transport tiny bubbles of air may have formed inside the glass

bulb. The electrode cannot function properly under these conditions.

These bubbles can be removed by "shaking down" the electrode as

you would do with a glass thermometer.

If the bulb and/or junction are dry, soak the electrode in HI 70300

storage solution for at least one hour.

Please note:

HI 8615 or HI 8615L

-1000 mV = 4 mA

0 mV = 12 mA

1000 mV = 20 mA

350 mV = 14.8 mA

200 mV = 13.6 mA

275 mV = 14.2 mA

1 mV = 12.008 mA

Note: When the HI 8615

and HI 8615L

are used in conjunction

with the Hanna new HI 8512 indicator or HI 8720 controller,

the calibration can also be performed on the indicator/

controller. In this case slight adjustment can be made on the

indicator/controller even if the whole system calibration is

advised, always starting from the transmitter.
