Taking a Measurement
Assemble the probe and connect the needle probe tubing to the
intake of the F-940. Twist on a hydrophobic filter to the end of
the tubing. The filter will prevent any moisture or debris from
entering the instrument. [NOTE: Failure to use a hydrophobic
filter risks drawing liquids into the instrument, which can
potentially damage the instrument sensors.] Finally, attach a
sterile needle to the filter. Depending on the application,
needles can be re-used.
