USER GUIDE
Carefully adjust the pot until the display matches the reference. Next lower the grid to around -30⁰ and -20⁰ checking each time
that the reference and reader displays match. It may be necessary to re-adjust the zero measurement following calibrating the
span, in which case check the span calibration again.
Once completed you should fix a label over the two controls to prevent accidental adjustment and mark the date of calibration.
Make a note in your diary, calendar or smart phone for 12 months' time to check the calibration again.

Battery Replacement

If the Inclinometer display fails to power up, shows a dim read-out or a low battery warning you need to replace the internal
battery. The display uses a 9V PP3 style battery; always use an alkaline replacement from a reputable manufacturer such as
Duracell, Maxell, Energiser et cetera.
The battery is accessed by opening the reader case completely; there is no dedicated battery compartment. The case separates
into two halves dividing down the middle. The case clips together, there are no screws to remove. The best tool to use is a
medium (around 5mm) flat blade screwdriver. Insert the blade of the screwdriver into the slot at the left hand end of the case
and carefully twist to ease the case apart. Now move the screwdriver to the top of the case around three quarters of the way
along towards the right hand end and twist the blasé again in the slot to ease the case further apart. Repeat this at the bottom
and the case should be unclipped sufficiently to make it easy to pull completely apart. The battery is in the upper half with the
rest of the circuitry, with the reader top half face down it is in the bottom right corner;-
