This meter is not legal for trade applications.
The meter is very sensitive to electrical "noise"
and may not operate correctly if located near some
electrical equipment.
CALIBRATION
This meter has a permanent factory calibration
for measuring water. If installed and used correctly,
inaccuracies of no greater than ±5% will be ob-
tained.

OPERATION
Batch and Cumulative Totals
The meter maintains two totals. The batch total
may be reset to measure flow during a single use.
The cumulative total provides continuous mea-
surement and may not be manually reset. The
batch total is labeled as TTL1. The cumulative total
is labeled TTL2.
When the cumulative total reaches a maximum
reading of 9999, it will automatically reset to zero.
Press the DISPLAY button briefly to switch
between the batch and cumulative total.
Activate the Meter
Turn the meter ON by starting water flow or
briefly pressing the DISPLAY button. The meter will
display the batch or cumulative total from last use.
Press DISPLAY briefly to display the batch
total. Hold the DISPLAY button down for three
seconds to reset the batch total to zero.
The meter is programmed to turn off automati-
cally if not used for about one minute.
MAINTENANCE
Proper handling and care will extend the life
and service of the meter.
Turbine Rotor
The meter is virtually maintenance-free. How-
ever, it is important the rotor moves freely. Keep the
meter clean and free of contaminants.
If the rotor does not turn freely, apply a pen-
etrating lubricant on the rotor, shaft, and bearings.
Remove any debris or deposits from the rotor using
a soft brush or small probe. Be careful not to
damage the turbine rotor or supports.
CAUTION: Blowing compressed air through
the turbine assembly could damage the
rotor.
