Measurement signal errors
are displayed at the top of
the display instead of the
measurements and statis-
tics. The message «Signal
failure» appears on the LCD
screen with 2 values (Fig.
65) A = X.X Volt and
dt = X.X ms
10.3 Description of the measurement
signal errors
With the impact devices type P, PG and U with error
A = X.XX V
If the A-value is below 3.30 V.
a C lean the impact bodies and guide tube.
Refer to section 11 «Maintenance»
If the A-value is higher than 4.00 V.
a R epeat the measurement with a slower loading
movement (section 10.1).
With the impact devices type P, PG and U with error
dt = X.XX ms
If the dt-value is lower than 0.40 ms
The support ring is worn; i.e. the impact body is in
a
an incorrect position at the time of measurement.
Replace the support ring.
On impact device type P with error dt = X.XX ms
If the dt-value is higher than 1.25 ms
The support ring is not correctly positioned.
