CAUTIONS
• Always operate this instrument at room temperature between 41°F and
122°F (5°C to 50°C). Allow sufficient air circulation by leaving at least 6
inches (15 cm) of clearance around the instrument. Overhead clearance is
required. DO NOT place unit under any structure.
• Component lifetime can be shortened by continuous high temperature op-
eration.
•
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 Maintenance, Section .)
•
DO NOT apply any type of voltage to the display hold terminals. Apply
-
ing a voltage to the terminals may cause damage to the controller.
•
DO NOT use fluids to clean out the well. Fluids could leak into electron
-
ics and damage the instrument.
•
Never introduce any foreign material into the probe hole of the insert.
Fluids, etc. can leak into the instrument causing damage.
•
DO NOT change the values of the calibration constants from the factory
set values. The correct setting of these parameters is important to the
safety and proper operation of the calibrator.
•
DO NOT slam the probe sheath in to the well. This type of action can
cause a shock to the sensor and affect the calibration.
