Cautions

To avoid possible damage to the instrument, follow these guidelines:
To properly calibrate the Metrology Well, the "Fan Limit" must be set to "Auto."
DO NOT leave the sleeve(s) in the instrument for prolonged periods. Due to the high
operating temperatures of the instrument, the sleeves should be removed after each use
and buffed with a Scotch-Brite® pad or emery cloth (see the Maintenance section of
the Technical Guide).
Always operate this instrument at room temperature between 5°C and 50°C (41°F
and 122°F). Allow sufficient air circulation by leaving at least 6 inches (15 cm) of
clearance around the instrument. Overhead clearance is required. DO NOT place the
instrument under any structure.
DO NOT interchange inserts between Metrology Well models. The inserts provided
with the instrument as well as any additional inserts ordered are model specific.
Component lifetime can be shortened by continuous high temperature operation.
DO NOT apply any type of voltage to the switch terminals. Applying a voltage to the
terminals may cause damage to the controller.
DO NOT use fluids to clean out the well. Fluids could leak into electronics and dam-
age the instrument.
DO NOT introduce any foreign material into the probe hole of the insert. Fluids, etc.
can leak into the instrument causing damage.
