GENERAL

DESCRIPTION

The A771 is an advanced state-of-the-art Carbon

Monoxide monitor that may be used to measure

levels of carbon monoxide (CO) in th part per

million (ppm) range when used with a digital

multimeter (DMM).

The instrument has both audible and visual alarms

when CO has reached the preset level. This unit

may be operated as an alarm only personal

monitor.

NOTE: The product may be used with any DMM

capable of measuring 2-4 volts DC. The signal

output is 1 mV DC = 1 ppm CO.

The A771 uses and advanced electrochemical

sensor that measures Carbon Monoxide only. A

built-in filter reduces most cross-sensitivity to

other gases. This product should be used with

DMM’s with greater than or equal to 10 megohm

impedance.

OPERATION

(Investigation Use)

1. Attach the banana jack to the COM and V input jacks

of the DMM.

2. Turn on the DMM and select the 2 or 4 volt range

DC.

3. If the voltage reading is below 4 VDC with the A771

in the off position, replace the 9 volt battery in the

A771.

4. Turn on the A771. The alarm LED with flash and the

green LED should stay on.

5. In a clean environment, adjust the zero knob until

the DMM reads zero.

6. Place the A771 in the area to be tested and read the

CO in ppm on the DMM.

7. To deactivate the alarm sound, set the slide switch

to MUTE.

OPERATION

(Monitor Use)

1. Follow steps 1-5 above.

2. Unplug the A771 from the DMM.

3. Place the A771 in the belt pouch with the sensor

facing outward.

4. If an alarm occurs, use a DMM to measure the

concentration.

5. The red LED will illuminate continuously during

alarms

ALARM ADJUSTMENT

The alarm on the A771 is factory set at 30ppm. Use

the following procedure to select a different level

between 0 and 200ppm:

1. Remove the battery compartment cover on the

A771.

2. Using a DMM set to the DCmV range, touch the tips

of the test leads to the GND and Alarm test points on

the PCB (located on the left and right next to the

VR1 and VR2 adjustment pots).

3. Reading the DMM, set the alarm to the desired level

(1ppm = 1mV DC) by adjusting VR2.

4. Remove the leads and reassemble the A771.

CALIBRATION

1. Attach the banana jack to the COM and V input jacks

of the DMM.

2. Turn on the DMM and select the 2 or 4 volt range

DC.

3. If the voltage reading is below 4 VDC with the A771

in the off position, replace the 9 volt battery in the

A771.

4. Turn on the A771. The alarm LED with flash and the

green LED should stay on.

5. In a clean environment, adjust the zero knob until

the DMM reads zero.

6. Attach proper gas, regulator and adapter assembly

to the A771.

7. Allow to stabilize for 1 minute.

8. Adjust VR1 in the battery compartment to the

proper gas value.

9. Disconnect gas and allow A771 to zero.
