REMOVING THE PORT PLUGS
Using the long extended end of the probe installation tool supplied in the YSI 6570
Maintenance Kit, remove the port plugs. Save all the port plugs
for possible future use.
There are a variety of probe options for the sondes. Figures 15, 16 and 17
illustrate the uses of the common tool for port plug removal.
Note that this tool will also be used to install the various probes.
If the tool is misplaced or lost, you may use 7/64" and 9/64" hex keys as
substitutes.
