The 5905/200-BOD/Pro-BOD must be plugged into a YSI meter
and the stirrer power plug must be plugged into its power
adapter. The 5010 must be plugged into a YSI meter only, as it
gets its stirring power from the 5000/5100 instrument.
Changing the Membrane Cap
---IMPORTANT---
New Probe Use
New probes are shipped with a dry membrane cap to protect the
electrodes. A new membrane cap must be installed before first
use. For the 5905/5010, use a Teflon membrane from a 5906
Membrane Kit. For the 200-BOD/Pro-BOD, use a PE membrane
from a 5908 Membrane Kit.
Follow these instructions to change membrane caps (Figure 1):
1. Remove the stir paddle from the probe by pulling it straight
out.
2. Unscrew the old membrane cap from the probe. Before
installing a new membrane, clean the probe tip with deionized
water in order to remove any contaminants.
3. Hold the membrane cap and fill it at least ½ full with the
electrolyte solution provided. Screw the membrane cap onto
the probe moderately tight. A small amount of electrolyte
should overflow.
4. Rinse off excess electrolyte from the probe with deionized
water.
5. Reinstall the stir paddle.
