Instructions for re-calibration

1. Check the Meter against a 2-liters measure.

If the reading on the Meter is out of calibration, note the

displayed volume (e.g. 1.98) and calculate the new Scale

Factor (e.g. 1.0101) as shown in illustration to the left.

Note! If the meter already has a Scale Factor other than

the default figure 1.0000 set it back to 1.0000 (see point

3-5.) before performing the calibration. To check the

actual Scale Factor, simultaneously press the RESET

1 0 1 0 1

and SELECT buttons (press RESET slightly before

1 9 8

SELECT).

New Scale Factor

2. Remove the hexagon screw that covers the SETUP

button.

3. With a sharp object, like a small screwdriver, short-

circuit the two soldered pads on the circuit board that

can be reached through the hole. These must remain

short-circuited during the entire setting procedure.

4. The actual Scale Factor is now shown on the display.

Set the new Scale Factor as shown in the diagram. Use

the SELECT button to move to desired position and the

RESET button to change the numbers.

5. Release the SETUP button and test the Meter against

the 2-liters measure. If the Meter reading is accurate,

replace the hexagon screw.
