USB INTERFACE
WARNING - The Thermometer must be turned
OFF before connecting / disconnecting a personal
computer or a power supply through the MicroUSB port.
The OMEGA® HH42A has a Micro -USB
port. The USB port serves two purposes:
It •
allows a personal computer to
communicate with the thermometer.
•
It provides external power to the
thermometer.
The HH42A comes with a powerful software
program called t-View. This software
communicates with the thermometer,
displays real-time data and graphs, and
allows for data logging and exporting to
Excel® file format.
The USB port is also used to provide
external power to the thermometer. Anytime
the thermometer is connected to a personal
computer or a 5V USB power supply, it is
powered through the USB port. During this
time, battery power will not be drained.

BATTERY REPLACEMENT
Only use 9V alkaline battery,
Duracell MN 1604 or equivalent.
When replacing the battery, do the
following:
1. Place the thermometer onto its face
and remove the battery door at the
bottom of the case.
2. Carefully tilt the thermometer to one
side until the battery exits the battery
compartment.
3. Using your thumb and index fingers,
carefully squeeze around the middle
of the battery connector to
disconnect the old battery.
4. Be sure to line up the terminals of
the new battery with those of the
connector. Then, firmly snap the two
together.
5. Push the connected new battery into
the battery compartment. Ensure
connector wires will not block the
battery door by pushing them to the
side of the battery.
6. Replace the battery door into original
position.

CARE AND CLEANING
Extensive testing has proven the case of the
thermometer to be rugged and reliable. It is
splash resistant but not water proof. The
case may not be submerged! Liquid will
flow in and damage or ruin the thermometer.
DO NOT AUTOCLAVE THE UNIT!! If
it is necessary to decontaminate the
thermometer, a weak chlorine solution may
be gently wiped on to the case by a well
rung out soft cloth. Do not let any liquid go
into the jacks.
The clear plastic LCD lens can be easily
scratched and/or fogged by inappropriate
cleaning products. Use only plastic approved
lens cleaners. Alcohol, acetone, lacquer
thinners, and other harsh chemicals will fog
the lens and damage the case and rubber
keypad.
EITHER OF THE BELOW ACTIONS
CAN VOID OMEGA ENGINEERING
WARRANTY:
WARNING – Never use
alcohol or thinners as these
will damage the instrument.
WARNING – Do not use
outside of specified operating
ranges and conditions, or
outside of normal laboratory
environments or applications.
