Ada AngleMeter 45 Operating Manual page 7

This is done by placing the molding as shown in pic. 6. Once the arms are set
to matching the angle of the item, press the HOLD/SUP button (11) for ~2
sec to get the supplemental angle. That will be the spring (SPR) angle.
EX: Angle between arms = 135°
Supplemental angle = 45°
Step 1: Start compound mitre mode. Press the MITRE button (15) for ~2
sec. The SPR indicator (7) will flash and the SPR angle that was last stored
into memory will be shown for ~2 sec.
Step : The SPR indicator (7) will stop flashing and the display will again
show the active angle. If the stored SPR angle needs to be changed, adjust
the arms (13 and 16) until the displayed angle matches the known spring
angle (typ. 38° or 45°). Then press the MITRE button (15) for ~2 sec. The
displayed angle and SPR will flash once and the spring (SPR) angle is now
stored in memory.
If the stored spring angle does not need to be changed, press MITRE button
(15) for ~1 sec to move to the next step.
Step : If you do not already have the CNR indicator (6) shown in the dis-
play, press the MITRE button (15) for ~1 sec. The CNR indicator will flash
and the CNR angle that was last stored (6) into memory will be shown for ~2
sec. The CNR indicator (6) will stop flashing and the display will again show
the active angle. If the stored CNR angle needs to be changed, adjust the
arms (13 and 16) as shown in pic. 5. To store the corner angle into memory,
