Using And Calibrating The Compass - General DAF3012M User Manual

To delete an individual record, first make sure the meter is
operating in one of the three real-time measurement modes.
Then,
1. Press the RCL/DEL button to enter memory recall mode, with
Rec replacing JOB at the lower left of the LCD.
2. Press the SET button repeatedly until the record to be deleted is
on-screen, with its memory location number shown below Rec.
3. Briefly press (but do not hold) the REC button to delete the
record. This will change Rec to JOB (indicating exit from
memory recall mode) and change the readouts to the next-
newest pair of stored readings. If no newer readings have been
stored, the readouts will switch to the next-oldest pair of
readings.
To bulk-erase the memory (delete all records), press and hold
the REC button for at least 2 seconds with the meter operating in
one of its three real-time measurement modes. This will reset the
memory counter to 01.

USING AND CALIBRATING THE COMPASS

The DAF3012M is equipped with a magnetometer (electronic
compass) capable of displaying direction within 45 degrees using
the standard terms N, NE, E, SE, S, SW, W and NW. Bearings are
simultaneously shown in two places: in the upper left corner of
the LCD (Fig. 2, Callout Q), and below it at the end of an arrow
pointing in that direction (Callout P).
To provide accurate readings, the compass should be calibrated
after each battery replacement. To begin the calibration
process, take the meter outdoors to minimize the effects of
indoor electromagnetic interference (EMI). Then:
1. Use the MODE and SET buttons to place the meter in air/wind
speed measurement mode, with VEL visible but not flashing on
the top line of the LCD.
