ThermoWorks 9141 HART SCIENTIFIC FIELD DRY-WELL TEMPERATURE CALIBRATORS - Manual (Page 17)

4 Quick Start
4.1 Unpacking
Unpack the dry-well carefully and inspect it for any damage that may have oc-
curred during shipment. If there is shipping damage, notify the carrier
immediately.
Verify that the following components are present:
• 9141 Dry-well
• 3141-2, Insert A
• Power Cord
• Manual
• Report of Calibration
• Calibration Label
• Heat Shield
• 9930
• RS-232 Cable
• Insert Removal Tool
4.2 Set-Up
Place the calibrator on a flat surface with at least 6 inches of free space around
and 18 inches above the instrument. Plug the power cord into a grounded mains
outlet. Observe that the nominal voltage corresponds to that indicated on the
back of the calibrator. Place the heat shield on the unit to deflect high tempera-
tures from the probe hubs (see Figure 1 on page 5).
CAUTION: The heat shield may become very hot. Use extreme caution.
Carefully insert the probe sleeve into the well. (DO NOT drop the sleeve in the
well.) Probe sleeve holes should be of the smallest diameter possible while still
allowing the probe to slide in and out easily. Sleeves with various hole sizes are
available from Hart Scientific. The well must be clear of any foreign objects,
dirt and grit before the sleeve is inserted. The sleeve is inserted with the two
small tong holes positioned upward.
Turn on the power to the calibrator by toggling the switch on the power entry
module. The fan should begin quietly blowing air through the instrument and
the controller display should illuminate after 3 seconds. After a brief self test
the controller should begin normal operation. If the unit fails to operate please
check the power connection.
