1.2 Safety Information
Use this instrument only as specified in this manual. Otherwise, the protection
provided by the instrument may be impaired.
The following definitions apply to the terms “Warning” and “Caution”.
•“Warning” identifies conditions and actions that may pose hazards to the
user.
•“Caution” identifies conditions and actions that may damage the instru-
ment being used.
1.2.1 Warnings
To avoid personal injury, follow these guidelines.
•DO NOT use this unit in environments other than those listed in the
User's Guide.
•Follow all safety guidelines listed in the User's Guide.
•Calibration equipment should only be used by trained personnel.
•The AC adapter can present safety concerns if misused or damaged. To
avoid the risk of electric shock or fire, do not use the AC adapter outdoors
or in a dusty, dirty, or wet environment. If the cord, case, or plug of the
adapter is damaged in any way, discontinue its use immediately and have
it replaced.
•Never disassemble the AC adapter. Use only the AC adapter provided
with the instrument or equivalent adapter recommended by the manufac-
turer of this instrument.
•The AC adapter has circuits with high voltage inside that could present
danger of electrical shock or fire if exposed. If the AC adapter is damaged
in any way or becomes hot, discontinue its use immediately, disconnect it

CAT
from any AC supply, and have it replaced. Do not attempt to open, repair,
or continue using a damaged or defective AC adapter.
•The instrument battery can present danger if not handled properly. To
avoid the risk of exposure to dangerous substances or explosion, immedi-
ately remove the battery and discontinue use if it leaks or becomes dam-
aged. Never allow the battery to be shorted, heated, punctured, or
dropped. If the instrument is physically damaged, immediately remove
the battery to insure that it does not become shorted. While removed from
the instrument, store the battery in a location so that it will not come into
contact with metal or fluids that might short circuit the battery and where
it is safe from excessive temperatures.
•Used batteries must be disposed of properly. Check your local regulations
for additional information. Never dispose of batteries in fire which may
result in explosion with the possibility of personal injury or property dam-
age.
1.2.2 Cautions
•If the instrument is dropped, struck, or handled in a way that causes inter-
nal or external physical damage, immediately unplug the AC adapter, re-
move the battery, discontinue use, and contact an Authorized Service
Center. Do not attempt to disassemble or repair the instrument, battery, or
AC adapter. Refer repairs or replacement components to an Authorized
Service Center.
•The instrument and sensors are sensitive and can be easily damaged. Al-
ways handle these devices with care. DO NOT allow them to be dropped,
struck, stressed, or overheated.
•Sensors are fragile devices which can be damaged by mechanical shock,
overheating, and exposure to fluids. Damage may not be visibly apparent
but can cause drift, instability, and loss of accuracy. Observe the following
precautions:
•DO NOT allow sensors to be dropped, struck, or stressed.
•DO NOT overheat sensors beyond their recommended temperature range.
•Keep the sensors clean and away from fluids and dust.

2 Introduction
The Hart Model 1620 is a low-cost, high-accuracy, digital thermo-hygrometer.
Its unique combination of features makes it suitable for a wide variety of appli-
cations from laboratory to industrial ambient measurement. Features of the
thermo-hygrometer include:
•Two channels measure ambient temperature to ±0.125 C and %RH to
±1.5%
•Two sensors, each measuring temperature and relative humidity; each is
detachable, cable-extendable, and interchangeable, with self-contained
calibration; each may be assigned a unique 16-character identification
•Display resolution is user selectable up to 0.001 C and 0.01% RH
•On-board memory holds up to 400,000 time/date-stamped readings
•Removable data card option for additional data storage and ease of data
transfer to and from a PC.
•Visual and audio alarms for various alarm or fault conditions
•May be wall mounted or set on a bench top
•Detachable sensors contain their own calibration data for easy
recalibrations
•Optional software logs in real-time or shows graphical/statistical data
from data card (Data card is optional and not needed to run the software
for real-time logging.)
•Password protection of settings
•Large, monochrome LCD, displays temperature and humidity data graph-
ically, numerically, and statistically; 16 pre-defined, user-changeable
screen setups; display viewable in bright or dim lighting
•Serial RS-232 and IR interface standard
•Power 12 VDC from external 110-240 VAC to DC converter.
•Uses a standard 9V battery backup to allow continued measuring during
power interruptions.
•Certificate of NIST-traceable temperature and humidity calibration with
three each temperature and humidity points
