Operation
Leak Detection
1. Press the ON key to power the detector
2. Hold the CO52 steady in clean ambient air during its 30 second warm up which is
indicated by the flashing PPM symbol. When completed the PPM symbol will stop
flashing and a steady ticking noise will indicate that the CO52 is ready for use.
3. Trace the CO52 around the source of the suspected leak. When leaking gas is
detected the tone will increase in pitch with increasing gas concentration.
Digital display
The digital display indicates increasing gas concentration by a three range display.
Greater than 10000 ppm
Greater than 1000 ppm but less than 10000 ppm

Less than 100 ppm
Automatic Back Light
The CO52 will automatically reset itself to zero on activation. If necessary the CO52 will enter
into an automatic cycle to reset its zero. In this instance the unit will alarm at peak level and
decrease to zero. This process takes about 20 seconds.
Automatic Back Light
The CO52 has an automatic back light for the display, which switches on automatically in low
light conditions.
Batteries
2 AA size batteries are used. The battery compartment is located at the rear of the CO52. Fit
the batteries in accordance with the diagram found within the molding. Remaining battery life
is indicated by the symbol in the digital display. If the batteries are fresh, 5 segments will be
displayed.
Switch Off.
Switch the CO52 off by pressing the single on/off key. Store the CO52 in a warm dry place.
Warning! Storing in a damp environment will damage the sensor!
