OPERATION
Sensor / Charge LED
The C16 is equipped with a sensor / charge LED to give the user a visual indication that
the sensor is ready for immediate use. This LED will flash about every 3 seconds. The sensor
LED will flash even when the batteries in the C16 are too low to run the instrument. If the
instrument will not start, replace the D-Cell and recharge the secondary battery. If the sensor /
charge LED is not flashing the sensor has lost BIAS and may require several hours to stabilize.
Replace the D-Cell and recharge the secondary battery.
The C16 Leak Detector is shipped ready to use directly out of the box. No adjustments of
any kind are necessary. Simply remove the instrument from the storage case and press and
release the green button below the display. The audible horn will beep once and the internal
pump will begin to pull sample into the flow manifold.
CAUTION:
For the instrument to work properly, the INLET and OUTLET ports on the
back of the instrument must not be blocked or obstructed.
When power is first applied, the LCD display will scroll through a number of different
start-up displays. The meaning of these displays will be explained in later sections of this
manual. However, these displays will not affect the use of the instrument in making gas
measurements as soon as power is turned on. Let the start-up displays cycle through until the
display stops at the main display (or press the SKIP key). The unit will indicate gas concentration
in large numbers, with the gas symbol and units of measure to the right of the number. Figure 2
shows how the main display will look initially.

To use the detector immediately, remove the sampling wand from the carrying case and
plug it into the mating connector on the back of the flow manifold. The internal sample pump will
draw gas samples through the wand and display the concentration on the LCD. No adjustments
are needed. However, you should run a response test as described on the next page, prior to
using the instrument.
When you have finished using the detector, press and hold the green switch (marked Off
on the LCD) until the LCD indicates the message “POWER DOWN”. Release the switch and the
unit will shut off.
