I. GENERAL DESCRIPTION

The CAL-101 is a small, battery-powered, portable electrochemical gas

Internal Micro Pump

A small air pump draws in ambient air to blend with the electrochemically

generated gas.

Electrochemical Generating Cell

The electrochemical generating cell contains an electrolyte solution and

either inert or consumable electrodes, depending upon the gas being

generated. A precise concentration of gas is produced when the CAL-101

supplies a known amount of current and a known amount of air continuously

to the cell.

Alkaline "AA" Batteries

A set of two fully charged alkaline "AA" batteries provides 10-12 hours of

operation. To replace the batteries, first remove the cell then slide the battery

chamber in to allow the batteries to drop out the bottom of the instrument.

NOTE: Rechargeable batteries will provide substantially fewer hours

of operation and will self discharge while the instrument is in storage.

Users should also be aware that use of rechargeable batteries will void

the CSA approval of the CAL-101 for intrinsic safety.

Microprocessor-Based Circuitry

When powered-up, the microprocessor provides remaining cell and battery

life indication via the display LEDs. Low battery or exhausted cell conditions

are also indicated when the condition occurs. (See section IV Non-Normal

Operation.)

generator designed to calibrate toxic gas sensors.

Fast warm-up time allows the instrument to be turned

off between remotely located sensors saving battery

life and avoiding generation of unwanted gas. The

CAL-101 uses the following components to produce

the calibration gas/air mixture:
