OPERATION
Ensure adequate ventilation during operation, Chlorine (even at low concentra-
tion) can be harmful. See MSDS for further product safety information.
1. Open front cover to expose control panel.
2. Check ‘CELL LIFE REMAINING’ indicator has not reached 0. If indicator
has reached 0, do not attempt to use as the generating cell needs to be
replaced. The generating cell can be replaced by either:-
a. returning the GazCalTM to Gastech (or local representative) or,
b. fitting a new cell yourself – new cells from Gastech come with full in-
structions.
3. Push outlet pipe firmly into gas outlet connector.
4. Toggle ON/OFF switch to ‘ON’ position. If low battery symbol appears on
the display, switch instrument ‘OFF’ and connect ‘GazCalTM CHARGER’
via charge socket and charge instrument for eight hours. Alternatively the
instrument can be run from the charger.
5. Ensure ‘BLOCKAGE’ LED is not illuminated. If the ‘BLOCKAGE’ LED is illu-
minated, check outlet pipe for blockages. If the ‘BLOCKAGE’ LED remains
illuminated the internal air filter may need replacing. The life of the air filter
depends upon the atmosphere which the instrument is used in, but should
always be replaced every 3 MONTHS.
6. Rotate ‘PPM ADJUST’ knob until the desired concentration is dis-
played. Allow 3 minutes for the generating concentration to stabilise. The
instrument is now ready for use. Note the GazCalTM has been designed
to work in the upright position, but can be used with the front cover either
open or closed.
7. Before switching the GazCalTM ‘OFF’, the instrument must be purged. To
purge the instrument, simply rotate the ‘PPM ADJUST’ knob until 0.0 PPM
Cl2 is displayed, and allow instrument to run for one minute before switching
instrument ‘OFF’.
8. Remove gas outlet pipe by pressing release ring of outlet connector to-
wards the case, and pull gas outlet pipe out of outlet.
