7.2 Pulse Inputs are not Counting on the Instru-
ment
A. Check the voltage of the pulses. They must be between
3-30V, and not less than 3 V or negative.
B. Check pulse width. Pulse width of the signal must be
consistent with the filter that you have selected. If this is
not the case, change the filter value.
7.3 Instrument Needs to be Totally Re-initialized to
Clear Out the Memory.
Power up the instrument and press the A and the CLR
keys at the same time. This will totally reinitialize the
instrument. All parameters will be reset to their default
values. The unit will require you to input the parameters
that have null values and select the various options avail-
able.
