DIESEL SMOKE METER (DSM) FAULT FINDING
Battery Charging
The DX260-1BT wireless Smoke head contains a Multi-Cell Rechargeable Battery designed to give
a maximum of 1.5 hours endurance from a full charge.
The smoke head must always be replaced on the charging cradle in between tests.
It is also strongly recommended that the batteries be completely discharged on a monthly basis
by setting the program to Live Readings with the smoke head off the charger.
Please note that rechargeable batteries have a nite lifespan, therefore the battery pack will need
to be replaced periodically if the smoke head is no longer sustaining suicient charge for correct
operation.
LED Indica�on
Smoke head removed from charging cradle:
• LED ‘On’ continuously:
Smoke head is running on internal battery
• LED pulsing ‘ON’ for 2 seconds, ‘OFF’ for 0.5 seconds:
Smoke head battery has reached a Low Voltage condition, and has less than 10 minutes
life left before auto-shutdown.
• LED ‘OFF’:
Low Voltage condition. Smoke head will auto shut down. No more testing possible until
smoke head battery has been recharged.
If the smoke head has received no communication from host computer for over 6 minutes it will
go into ‘Sleep’ mode. Return the smoke head to the charging unit to invoke a response.
If the smoke head is taken outside its maximum operating range of about 100 metres, and wireless
communication is no longer possible, after 6 minutes the smoke head will go into ‘Sleep’ mode.
To recover from ‘Sleep’ mode, the smoke head should be put back in its charging cradle, and the
LED function observed.
Smoke head returned to Charging Cradle:
• FAST CHARGE (2.5 flashes per second):
The Smoke head is in ‘Fast Charge’ Mode. The battery should fully charge within 1.5 hours
• TOP-UP CHARGE (1 ash per second):
The Fast Charge cycle has completed and the battery is being brought to full charge
• SLOW CHARGE (1 ash every 2 seconds):
The Smoke head battery is in ‘Slow Charge’ mode, the charging rate determined by either
terminal voltage or, battery cell temperature

Battery Charging cont.
• TRICKLE CHARGE (1 flash every 3 seconds):
LED Flashing ON/OFF shows the smoke head battery is in ‘Trickle-Charge’ mode
indicating that the batteries are fully charged.
Fault Diagnosis:
• FAST FLICKER (8 flashes per second or more):
The smoke head has detected poor charging contacts. Clean the contacts on both the cradle and
the smoke head feet and replace on charger
• LED NOT ILLUMINATED:
Return the Smoke head to Charging Cradle. LED should display according to Charging level
required.
• LED NOT ILLUMINATED WHEN SMOKEHEAD IS ON CHARGING CRADLE:
• Check that the smoke head is correctly seated on the charging cradle. The smoke head
has twin connectors on each insulated foot, and may be connected either way round
• Check the charging cradle is connected to the 240V AC mains
• Check that the sprung connectors that transmit the charging current on the charging
Cradle are clean and not stuck in a depressed condition.
• Check that the charging connectors on the insulated mounts on underside of the smoke
head are clean and free of dirt and obstructions.
To check the charging voltage at the charging cradle:
• Connect a digital multi-meter set to measure up to 30V DC to the two charging
• Connectors on the charging cradle and depress the central charging switch
• A voltage of 28V to 30V DC should register on the multi-meter display
