Output Data Separator: Default separator at power-on
is LF. The separator can be programmed to be any non
printable ASCII-code with decimal equivalent 0-31, ex-
cept 27 (ESC).
In addition the combination 13+10 (CR+LF) can be pro-
grammed. The EOI-line can be programmed to be active
together with the last output byte sent.
Output Format:
Measuring result is sent as:
Function code 3 to 6 characters
Normally space. O on overflow
Measuring result
Exponent pointer
Exponent sign (+ or -)
Exponent value 0 to 9
Selected separator
Second separator
LF only if output
separator CR+LF
has been selected.
FFFFFFOXXXXXXXXXXE±XS(S)
21(22) characters.
When you select ’Short output format’ FFFFFF and lead-
ing zeroes are omitted.
High-Speed Dump
The contents of the counting registers are transferred to
the controller, without being processed by the counter.
The processing must be done in the controller instead.
Max output rate is approximately 100 readings/s.
The output format is FMXXXXXXXXXXXXS(S) where F
is calculation formula, M is multiplier, X..X = 12 hex-dig-
its representing the register contents, and S(S) is the set
output separator.
Ranges: Same as for normal operation, with the following
exceptions:
Frequency;
Max measuring time: 1 s
Period, Average;
Max measuring time: 1.4 s
Time Interval, Average;
0 ns to 1.6 s
Max measuring time: 4 s
Ratio A/B:
0 and 6*10
-7
to 1.6*10
8
Ratio B/A:
0 and 6*10
-8
to 1.6*10
7
Ratio C/A, C/B:
8 to 4*10
9
Max Data Output Rate: Normal mode gives >5 read-
ings/s. High-speed dump gives >100 readings/second.
The highest output rate is obtained at SINGLE Measur-
ing-time.
Output Time for Measuring Data;

Response Time for Trigger Command (GET):
Normal Operation:
Approx. 10 ms
High-Speed Dump:

Response Time for Serial Poll: Approx. 1.5 ms
Input Buffer Size: 28 bytes
Typical Read Time for Programming Data: Ap-
prox. 1 ms/byte (unless input buffer is full)
