INSTALLING THE ISE PROBES
Figure 28
The Ammonium, Nitrate and Chloride ISE probes do not have slip
nuts and should be installed without tools. Use only your fingers
to tighten. Any ISE probe can be installed in any of the three ports
labeled “3”, “4”, and “5” on the sonde bulkhead of the 6820V2-1,
6920V2-1, and 6600V2-2 sondes or the single ISE port on the
6820V2-2 and 6920V2-2 bulkheads. Be sure to remember
which sensor was installed in which port so that you will later be
able to set up the sonde software correctly.
Figure 29
IMPORTANT: Make sure that the probe nut or probe body
of the ISE probes are seated directly on the sonde bulkhead.
This will ensure that connector seals will not allow leakage.
INSTALLING THE PROBE GUARD
Included with each sonde is a probe guard. The probe guard protects the probes during calibration and
measurement procedures. Once the probes are installed, install this guard by aligning it with the threads on
the bulkhead and turn the guard clockwise until secure.
CAUTION:
Be careful not to damage the Rapid Pulse DO membrane during installation of the probe
guard.
Figure 30 shows the YSI 6820V2-1/6820V2-2/6920V2-1/6920V2-2 probe guard; the guard for the
6600V2-2/6600V2-4 is similar. The YSI 600R, 600QS, 600XL and 600XLM probe guards resemble
Figure 31.
