Step 2: Calculation of V
OQ
and Sensitivity
There are two ways to calculate the values for V
OQ
and Sensitivity.
Manual Calculation:
Set the system to calibration point 1 (angle 1 =
25
°
)
and read the register ADC-READOUT. For our exam-
ple, the result is ADC-READOUT1 =
2500.
Next, set the system to calibration point 2 (angle 2 =
25
°
), and read the register ADC-READOUT again. For
our example, the result is ADC-READOUT2 =
+
2350.
With these measurements and the targets V
OUT1
=
4.5 V and V
OUT2
= 0.5 V, the values for Sensitivity and
V
OQ
are calculated as
Software Calibration:
Use the menu CALIBRATE from the PC software and
enter the values 4.5 V for V
OUT1
and 0.5 V for V
OUT2
.
Set the system to calibration point 1 (angle 1 =
25
°
),
hit the button
“
Read ADC-Readout1
”
, set the system to
calibration point 2 (angle 2 = 25
°
), hit the button
“
Read
ADC-Readout2
”
, and hit the button
“
Calculate
”
. The
software will then calculate the appropriate V
OQ
and
Sensitivity.
This calculation has to be done individually for each
sensor. Now, write the calculated values with the
“
write
and store
”
command into the HAL 805 for program-
ming the sensor.
Step 3: Locking the Sensor
The last step is activating the LOCK function with the
“
LOCK
”
command. The sensor is now locked and does
not respond to any programming or reading com-
mands.
Warning: This register cannot be reset!
