Why calibrate?
If the meter is used:
• With fluids having the viscosity close to the limits of the allowed range (such as
low-viscosity antifreeze fluids or high-viscosity oils for gear boxes)
• In extreme flow rate conditions (close to the minimum and maximum value of
the allowed range), it may be necessary to carry out an on-site calibration
How to calibrate
The meter allows the user to carry out a rapid electronic calibration by modifying
the calibration factor (K factor)
At delivery all meters are given the same calibration factor:
K factor = 1.000
This calibration factor guarantees the best accuracy in the following operating
conditions:
Fluid: Motor oil type 10W 30 Temperature: 68°F Flow-rate: 2.8 GPM
The calibration can be done either as:
• An on-site calibration by dispensing into a calibrated container or
• A direct modification of the calibration factor
On-site calibration by dispensing into a
calibrated container:
Press and hold OK/STOP six times to set
the function.
The meter will display:
Blinking point
Press AUTO; start the calibration by
dispensing the fluid into a calibrated
container.
During dispensing the meter displays:
Batch Total dispensed
Blinking
The dispensing operation may be inter-
rupted and resumed.
The calibrated dispensing is complete
when the level of the fluid reaches
the graduated area of the calibrated
container.
The meter displays:
Indicated value
Carry out the calibration dispensing at
a steady flow rate by pulling the trigger
completely and keeping it in the open
position until the container is nearly full
is nearly full. Do not reduce the flow
rate to reach the graduated area of
the calibrated container. Instead, to
complete the final stages of the filling
operation into the calibrated contain -
er, top-off in small increments. This is
achieved by rapidly pulling the trigger
of the meter and then releasing it very
quickly.
WARNING In order to get a correct
Calibrated K Factor from the meter,
ensure calibration capacity is set
to more than 5 quarts. Purge all air
from the unit before carrying out the
calibration.
