ThermoWorks 9135-156 HART SCIENTIFIC 3-POINT IR CALIBRATOR - Manual (Page 13)

4 Quick Start
4.1 Unpacking
Unpack the calibrator carefully and inspect it for any damage that may have oc-
curred during shipment. If there is shipping damage, notify the carrier immedi-
ately. Verify that the following components are present:
• 9135 Calibrator
• Manual
• Report of Calibration
• Calibration Label
4.2 Set-up
Place the calibrator on a flat surface with at least three inches of free space
around the instrument. The prop may be swung down to tilt the instrument
from a horizontal position. Plug the power cord into a grounded mains outlet of
the proper voltage (see Section 4.3). Observe that the nominal voltage corre-
sponds to that indicated on the back of the calibrator.
Turn on the power to the calibrator by toggling the power switch on. The yel-
low LED corresponding to the 50°C set-point should immediately illuminate
and the calibrator should begin heating to 50°C. If the unit fails to operate
please check the power connection.
4.3 Power
The calibrator is configured for either 115 VAC (±10%), 50/60 Hz or 230 VAC
(±10%), 50/60 Hz using switches underneath. There are two switches and both
must be set to the correct voltage. One switch configures the power supply and
the other configures the heater. The calibrator can be switched in the field for
operation at either voltage as long as the following conditions are observed:
• The supply voltage must always match the switch settings! Operating this
instrument with the wrong supply voltage or switch settings will likely
damage the instrument and has the potential to start a fire.
• Both voltage switches must be set properly. Again, operating this instru-
ment with the wrong supply voltage or switch settings will likely damage
the instrument and has the potential to start a fire.
• Always unplug the instrument before changing the voltage settings!
Changing the voltage switches with power applied will likely damage the
instrument and has the potential to start a fire.
Use a small slotted-type screwdriver or equivalent instrument to change the
switches.
