Safety Information
GENERAL
The instrument does not come with a system cutout or cutout capability. The
user should provide a bi-metal cutout or other safety device for the system.
DO NOT use the 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.
DO NOT use the instrument in environments other than those listed in the
user's guide.
Follow all safety guidelines listed in the user's manual.
Calibration Equipment should only be used by Trained Personnel.
If this instrument is used in a manner not specified by the manufacturer, the
protection provided by the instrument may be impaired.
If the instrument is used to control a calibration heat source, be sure that the
heater is wired correctly (see Figure 1 on page 13).
Before initial use, or after transport, or after storage in humid or semi-humid
environments, or anytime the dry-well has not been energized for more than 10
days, the instrument needs to be energized for a "dry-out" period of 2 hours be-
fore it can be assumed to meet all of the safety requirements of the
IEC-61010-1. If the product is wet or has been in a wet environment, take nec-
essary 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.
The instrument is intended for indoor use only.
The instrument is a precision instrument. Although it has been designed for op-
timum durability and trouble free operation, it must be handled with care.
Operate the instrument in room temperatures listed in Section 2.2, Environmen-
tal Conditions. The instrument is not vented. Therefore, clearance for ventila-
tion is not a requirement. However, do not place the instrument on top of a
calibration bath or dry-well where it would be in contact or direct path of heat.
DO NOT stack items on top of the instrument.
BURN HAZARD
The instrument can be used to control instruments which generate extreme tem-
peratures. Precautions must be taken to prevent personal injury or damage to
objects. Probes may be extremely hot or cold when removed from a calibration
bath. Cautiously handle probes to prevent personal injury. Carefully place
probes on a heat resistant surface or rack until they are at room temperature.
Fires and severe burns may result if personnel fail to observe safety
precautions.
