Specific Parameters for TACV/P, DTACV/P
Scan Rate (mV/sec) = 4 1 to 200
A.C. Amplitude (mV) = 25 1 to 50
A.C. Frequency (mV) = 50 5 to 250
Drop Time (msec) = 500 500 to 8000
Quiet Time (sec) = 2 (0) 0 to 65535
Comments
a)
Drop Time
is used for
TACP
and
DTACP
. The range of values allowed for
the
Drop Time
depends on the
A.C. Frequency
. The analogous parameter for
TACV
and
DTACV
is the
Step Period
, which is controlled by the
A.C.
Frequency
(default value is 1500 msec).
b) Parameter values in parentheses refer to
TACP
and
DTACP
.
c) The sample interval is equal to the product of the
Scan Rate
and the
Drop
Time
(or
Step Period
) (e.g., the default value is 6 mV).
