PROBE PREPARATION

All probes are shipped dry by Hanna Instru-

ments. To hydrate the probe and prepare it

for use, connect it to the meter and proceed

as follows.

1 Remove the red and black plas-

tic cap which is for shipping

purposes and can be discarded.

2 Wet the sensor by soaking the

bottom 2½ cm (1") of the probe

in electrolyte (HI 7041S) for 5

minutes.

3 Take a membrane

(HI 76407A sup-

plied with the

meter) and Make

sure that the rub-

ber O-ring sits

properly inside

the membrane

cap.

4 Rinse the mem-

brane with electro-

lyte while shaking

it gently. Refill

with clean electro-

lyte.

5 Gently tap the sides of the membrane cap

with your finger tip to ensure that no air

bubbles remain trapped. To avoid damag-

ing to the membrane, do not tap the mem-

brane directly on the bottom.

6 With the sensor facing down, screw the

cap clockwise. Some electrolyte will over-

flow.

When not in use, protect the mem-

brane by placing the protective cap

on it.
