General Tools and Instruments CIH20DL - Manual (Page 5)

SAFETY INSTRUCTIONS
CAUTION!
The CIH20DL’s targeting laser is a Class II type that emits less than 1mW of power between
630nm and 660nm. Avoid direct eye contact with laser light radiation. U.S. law prohibits
pointing a laser beam at aircraft; doing so is punishable by a fine of up to $10,000 and
imprisonment.
WHAT’S IN THE CASE
The CIH20DL and its accessories come in a custom molded plastic case. The instrument
itself has two main components: a handheld meter with a digital display, and a telescoping
metal probe with two sensors at one end and a plug for connecting the probe to the meter
at the other. Also in the case are the following accessories:
• A USB cable for connecting the meter to a Windows computer, enabling the meter to
upload captured air speed, airflow volume and surface temperature data. This cable
has a mini B-type plug at one end and an A-type plug at the other.
• An AC adapter and power cable for connecting the meter to a 110V or 220VAC supply
to enable long-term data logging. This cable has a mini B-type plug at one end and a
socket with a spring-loaded latch at the other. The latch makes it easy to attach and
detach either of two kinds of plugs: one with American-style blades and the other
with European-style round prongs. One plug of each type is included in the case.
• A “9V” Alkaline battery.
• A plastic bag containing: 1) a CD with Windows-compatible software and drivers for
using the CIH20DL with a PC running Windows7 (32- or 64-bit), Windows Vista or
Windows XP; 2) a Certificate of Traceable Calibration; and 3) this user’s manual.
PRODUCT OVERVIEW
Fig. 1 shows the labels and positions of the controls and connectors on the front and
top of the CIH20DL. Fig. 2 shows all possible indications on the LCD. Familiarize yourself with
the controls’ functions and the meanings of the display indications before moving on to the
Setup Instructions.
1.
(Power) button
2. LCD with three readouts
3.
(Record) button: When pressed briefly, stores values shown on all three readouts in
one of nine nonvolatile memory locations, and then advances the location counter by one.
When pressed and held for 3+ seconds, begins logging measurement data (air speed or
airflow volume, air temperature and IR temperature) at preset sampling time. Logs are
stored in the meter’s internal memory space (as opposed to in nonvolatile memory). Also
used to change fields when setting sampling time, date or time and to clear the meter’s
internal data logging memory space.
