(2) Connect the sensor cable to the associated instrument correctly by referring to Section 2.3.
(3) Mount the liquid junction in the sensor body. Peel off the seal attached to the liquid junction
mounting hole on the sensor body. Screw the liquid junction gently two or three turns into the
hole.
(4) If specified, a reserve tank containing 250 mL KCl solution and mounting hardware to hold
this tank are supplied with the OR8EFG ORP Sensor. Attach the mounting hardware to
the pipe (2-inch). Connect the reserve tank to the KCl solution supply tube of the sensor.
Remove the cap from the tank and screw the tube connector securely into the tank.
(5) Supply KCl solution to the sensor. First, mount the reserve tank on the mounting hardware
with the tube connection part directed downwards. Using the pin supplied with the tank
make several holes in its top (see Figure 2.3). Stand the sensor upside down at a position
lower than the reserve tank as shown in Figure 2.3 so that KCl solution flows from the tank
into the sensor. When the KCl solution fills the sensor and overflows from the liquid junction
mounting hole, securely screw the liquid junction into the mounting hole.
(6) Screw the protector to fix the sensor to the holder. In this case, remove the protective cap
and secure the protector so that the flange of the sensor compresses the O-ring firmly.
