PROBE PREPARATION:
The meter is supplied with a 9V battery. Slide off the battery compartment cover on the back of the meter. Install the battery into the battery clip connector while observing polarity.
D.O. probes are shipped dry. Assemble the probe and prepare it for use, connect it to the meter and proceed as follows.
1. Remove the red and black plastic cap. This cap is used for shipping purposes only and can be thrown away.
2.Wet the sensor by soaking the bottom 2½ cm of the probe in electrolyte
(MA9071) for 5 minutes.
3. Rinse the membrane (supplied with the meter) with electrolyte while shaking it gently. Refill with clean electrolyte.
4. Gently tap the sides of the membrane with a pencil or a rod to disengage air bubbles. To avoid damaging the membrane, do not tap the membrane directly on the bottom.
5. Install
6.With the sensor facing down, screw the cap clockwise. Some electrolyte will overflow.
7.Examine membrane to verify air is not
trapped between the membrane and electrode tip.
When probe is not in use and during polarization, place the protective cap supplied over the electrode tip.
