Bias may be applied in the following two ways:
• Percentage:
A percentage of the actual value is calculated.
• Plus/minus:
A compensating value is added to or subtracted from the actual value.
1. Touch the converted velocity key (1) on
the measurement window (fig. 1) to
access the setting window (fig. 2).
2. Enter the converted velocity by touch-
ing the number keys (2). The accept-
able range is 1,200 - 2,000 m/s.
In the event of an erroneous entry,
touch the D
De elle ette e key (3).
3. Touch the R
Re ettu urrn n key (4) to set the
entered value.
4. Select either percent bias (%) or
plus/minus bias (
µ
m) at the bottom of
the window (5).
5. When setting percent bias, enter the
bias rate by touching the number keys
(2). When setting the plus/minus bias,
enter the compensating value by
touching the number keys (2). The
acceptable ranges are:
Bias rate (%): 60 - 130%
Compensating value: -600 - +450

In the event of an erroneous entry,
touch the D
