Functions and Features

General Features

The

2240

is designed as three section unit housed in a

tough ABS carrying case with all the necessary
accessories. The principle sections are:

•

Controller – Containing the user interface, battery, and
external electrical interfaces. (Serial and analog).

•

Wand Assembly – extends the operator’s reach by 24
inches,

making operation highly flexible.

•

Sensor Module – Containing the sensor element and
sensor-specific electronics. Easily mounted on either the
Controller or Wand Assembly.

Electrical Features

•

Power provided by either the internal battery or through an
optional

Teledyne

external power supply.

•

Automatic self-test, activated on start-up, to confirm
proper operation.

•

Serial Interface: 9 pin Sub-D connector in RS-232
configuration transmitting ASCII data in an 8 bit stream
with no parity and 1 stop bit.

•

Analog Interface: 0-5 V and 4-20 mA. (Reference Figure
3). The analog output produces a signal proportional to the
amount of hydrogen in air, an indication of Warm-Up
Mode, or an indication of Error Mode as determined by the
operator-selected format. (See section 5)

Operator Interface Features

•

LCD: provides readable (alphanumeric) information on
current readings and settings..

•

Tri-colored (green/yellow/red) LED: indicates instrument
status and changes in hydrogen concentration.

•

Audible alarm: Operator programmable level provides a
single beep each time a new peak hydrogen concentration
is detected and provides a continuous series of beeps if the
programmable Alarm setting is exceeded.
