Safety Information
or has been in a wet environment, take necessary measures to remove moisture prior
to applying power such as storage in a low humidity temperature chamber operating at
50°C for 4 hours or more.
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.
DO NOT place the instrument under a cabinet or other structure. Overhead clearance
is required. Always leave enough clearance to allow for safe and easy insertion and
removal of probes.
Use of this instrument at HIGH TEMPERATURES for extended periods of time
requires caution.
Completely unattended high temperature operation is not recommended due to safety
hazards that can arise.
If the instrument is used in a manner not in accordance with the equipment design, the
operation of the Metrology Well may be impaired or safety hazards may arise.
This instrument is intended for indoor use only.
BURN HAZARD
Each Metrology Well is equipped with a Block Temperature Indicator (front panel
LED HOT indicator – U.S. Patent 7,561,058 even when the instrument is unplugged.
When the indicator is ashing, the instrument is not powered and the temperature of
the block is above 50°C. When the indicator is illuminated, always on, the instrument
is powered and the block temperature is above 50°C.
DO NOT turn the instrument upside down with the inserts in place; the inserts will
fall out.
DO NOT operate instrument in any orientation other than vertical (block opening face
up). Risk of re or burn hazard may result due to excessive heat build up.
DO NOT operate on a ammable surface or near ammable materials.
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
Metrology Well.
The calibration well temperature of the Metrology Well is the same as the actual dis-
play temperature, for example, if the instrument is set to 700°C and the display reads
700°C, the well is at 700°C.
The air over the well can reach temperatures greater that 200°C for high temperature
(400°C and higher) Metrology Wells.
Probes and inserts may be hot and should only be inserted and removed from the
instrument when the instrument is operating at temperatures below 50°C.
