Operation
Getting Started
This section allows you to set up and start using the 373 right away. You’ll turn the system on
and quickly familiarize yourself with the layout and features of the display and touch screen.
Next, you’ll learn about the optical mirror assembly for later care and cleaning that may be
required. Finally, you’ll use the 373 to measure the dew point temperature. Set your 373 on the
bench and let’s get started!
Turning the 373 On and Off
The 373 needs a source of normal AC power. Have a look at the label on the back panel of the
instrument for the voltage required. Chances are, the required voltage matches that of your
standard laboratory power receptacles.
1. Using the supplied AC power cord, supply the proper voltage to the instrument by plugging
the cord into the back of the instrument, then into an AC receptacle of the proper voltage.
2. The power switch is located on the back panel next to the power cord input. Turn it ON.
The display should become visible within a few seconds. If nothing seems to happen, check the
power source. There may also be some fuses located next to the power switch. You can
remove and replace them with known good ones. Suspect fuses can be tested for continuity
with an ohmmeter.
What You See
When power is applied to the 373, the display will activate within a few seconds. A typical
display configuration is depicted below. If you or someone else previously configured your
system, it may look slightly different. But don’t worry, we’ll show you how to set it up the way
you like.
