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, inac­
curacies of no greater than ±5% will be obtained.
INSTALLATION
This meter may be installed in-line either horizon­
tally or vertically or at the end of the hose adja-cent

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 measure­
ment and may not be manually reset. The batch total
is labeled as TTL 1. The cumulative total is labeled
TTL2.
When the cumulative total reaches a maximum
9999,
reading of 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 automatically
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. However,
it is important the rotor moves freely. Keep the meter
clean and free of contaminants.
If the rotor does not turn freely, apply a penetrating
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.
