The PRESCALE command multiplies the Channel A
count by 16 before calculating FREQUENCY, PERIOD, RA-
TIO, and TOTALIZE. This command should be used when
a
divide by 16 prescaler is attached to Channel A, otherwise
erroneous measurelnents will result. Valid arguments are:
ON
-
The Channel A input is multiplied by 16 before
calculating results.
OFF
-
The Channel
A
input is not scalecl before the
results are calculated.
When the PRESCALE command is used and a compati-
ble prescaler is not connected to the DC 501 0 an execution
warning (ERR 604) is issued.
The power-on initial setting is PRE OFF.
