7.4 Acknowledging a fault message
In order to acknowledge the fault message and return to the ISOMETER®'s standard display, all
faults must be acknowledged by means of the "RESET" button.
This means that fault messages can only be reset when the cause of the fault has been elimi-
nated.
Press the "RESET" button, then and "OK" to clear the fault memory. The ISOMETER® returns
to the standard display.

100 measured values are available to represent each graph. and the resolution of each graph
is determined by these values.
