CAUTION
Do not attempt to set up the HERMIT without first becoming
thoroughly familiar with Appendix B; it contains informa-
tion that is important to avoid damaging your instrument
when it is set up.
Section 1: Introduction
Your HERMIT 2000 Environmental Data Logger is a versatile, self-
contained, and extremely rugged field instrument that enables you
to accurately perform a wide variety of hydrologic and environmen-
tal tests. To mention just a few of the special features of your HER-
MIT 2000, you have the ability to:
• Measure and record parameters such as level, flow, pressure, tem-
perature, conductivity, and pH using standard In-Situ transduc-
ers.
• Easily reprogram your HERMIT 2000 to measure and record pa-
rameters from most industry standard 4-20 mA (milliampere)
current loop transducers.
• Directly monitor and record flow from orifice plate discharge
pipes.
• Collect fast, accurate time-drawdown data from constant-rate or
stepped-rate pump tests, including the recovery phase. This pow-
erful feature is equally suited to slug tests.
• Perform unattended long-term monitoring of aquifers, lakes,
streams, reservoirs, waste-disposal sites, or any environment
where data collection is critical or difficult.
• Record data in as much as 512K bytes (524,288 characters of
information) of non-volatile data storage. Even if the HERMIT
2000’s battery pack should fail, data will remain safe.
• Display and report all measured parameters in their selected
measurement units. Data may be viewed on the large LCD (liq-
uid crystal) display, printed or plotted on an optional field printer,
or transferred to most personal and portable computers via the
built-in RS232C interface.
• Operate the HERMIT 2000 at extreme temperatures without hav-
ing to supply an external power source.
What’s New in Software Version 3.4
If you are already familiar with a previous version of the HERMIT
2000, you may want to take notice of several new features that have
been added to software Version 3.4:
• When you press
START
to begin a test with Level type inputs, the
HERMIT 2000 will ask whether you have set a reference. See Sec-
tion 7, Running a Test.
• When Level type inputs were used for a test, you can display the
reference level in PSI while viewing the test data. This informa-
tion is also printed in the data file header. See Section 8, Viewing
Stored Data, and Section 10, Printing Data.
How To Use This Manual
This manual has been designed to enable you to gain the maxi-
mum benefit from your HERMIT 2000 and to answer your ques-
tions concerning field installations. If you have just received your
new HERMIT 2000, read Appendix B before you attempt to operate
the instrument. Appendix B contains unpacking instructions and
other important owner’s information.
Then familiarize yourself with the HERMIT 2000 system by reading
and following through the examples in section 2 of this manual —
with your HERMIT 2000. The best way to feel at ease with the instru-
ment is to sit down with the operator’s manual and the HERMIT
2000 and actually key in the examples provided in each of the sec-
tions. It won’t take long to become familiar with your HERMIT 2000
and it is well worth the time invested to obtain a more complete
understanding of the instrument.
Sections 3 through 11 of the operator’s manual discuss each of the
programming and control features of the HERMIT 2000, in the or-
der you will most likely come to use them.
Sections 12 through 14 present field applications of the HERMIT
2000. The procedures presented in these sections will give you a guide
to programming the HERMIT 2000 to solve several common data-
collection problems.
After you’ve become familiar with the HERMIT 2000 system, you
may wish to enhance your data-collection capabilities with additional
inputs, expanded data storage, new types of transducers, and other
field accessories. Be sure to check the accessories list in Appendix A.
