BATTERY REPLACEMENT
1. Remove the protective rubber boot by slipping it
away from the bottom of the case and sliding it over
the pressure spigots exposing the case back.
2. Remove the battery cover from the bottom of the
case by removing the four screws.
3. Remove the three AA batteries and replace with
good quality AA Alkaline batteries taking care to
install them the right way round.
4. Replace the battery cover carefully making sure it is
alligned properly and replace the screws. Take care
not to over tighten the screws otherwise it may
damage the case.
For best results and longer life always use quality
alkaline batteries MN1500 or equivalent.
CAUTIONS
Exposure to silicone based products, corrosive gases,
water / condensation and freezing should be avoided
at all times as this will cause damage to the sensor
and internal component corrosion.
This instrument should not be stored or operated
outside of its operating temperature range.
Particular care must be taken not to exceed the
maximum pressure ratings for the device as this
may rupture the sensor membrane. This is not
covered by the manufacturer’s warranty.
NOTE: The differential/gauge instruments will only
measure positive pressures i.e. positive pressure
applied to positive port, or negative pressure applied
to the negative port.
WARRANTY
This instrument is guaranteed against defects of
workmanship and materials for a period of twelve
months from date of invoice.
During the warranty period a defective instrument will
be repaired or replaced at the discretion of the
manufacturer. This warranty does not cover damage
or failure due to misuse or accident. Modification,
adjustment or any alteration shall void the warranty.
For any warranty claims to be considered the
instrument must be returned to Anton along with proof
of purchase at the sender’s cost.
