DO NOT use this instrument for any application other than calibration
work. The instrument was designed for temperature calibration. Any other
use of the instrument may cause unknown hazards to the user.
Completely unattended operation is not recommended.
Overhead clearance is required. DO NOT place the instrument under a
cabinet or other structure. Always leave enough clearance to allow for
safe and easy insertion and removal of probes.
If the instrument is used in a manner not in accordance with the equip-
ment design, the operation of the dry-well may be impaired or safety haz-
ards may arise.
This instrument is intended for indoor use only.
BURN HAZARDS
DO NOT turn the instrument upside down with the inserts in place; the
inserts will fall out.
DO NOT operate near flammable materials.
Use of this instrument at HIGH TEMPERATURESfor extended periods
of time requires caution.
DO NOT touch the well access surface of the instrument.
The block vent may be very hot due to the fan blowing across the heater
block of the dry-well.
The temperature of the well access is the same as the actual display tem-
perature, e.g. if the instrument is set to 375°C and the display reads
375°C, the well is at 375°C.
For top loading dry-wells, the top sheet metal of the dry-well may exhibit
extreme temperatures for areas close to the well access.
The air over the well can reach temperatures greater that 200°C for high
temperature (400°C and higher) dry-wells. Note: Probes and inserts may
be hot and should only be inserted and removed from the instrument
when the instrument is set at temperatures less than 50°C. Use extreme
care when removing hot inserts.
DO NOT turn off the instrument at temperatures higher than 100°C. This
could create a hazardous situation. Select a set-point less than 100°C and
allow the instrument to cool before turning it off.
The high temperatures present in dry-wells designed for operation at
300°C and higher may result in fires and severe burns if safety precau-
tions are not observed.
ELECTRICAL SHOCK
These guidelines must be followed to ensure that the safety mechanisms
in this instrument will operate properly. This instrument must be plugged
into a 115 VAC, 60Hz (230 VAC, 50Hz optional), AC only electric outlet.
The power cord of the instrument is equipped with a three-pronged
9011 Dual-Well Calibrator
