* If Service request (SRQ) is enabled for an event, the
decimal value of the status message for that event
will be increased by 64. The reason for this is that
bit 6 will be set to one at the same time as the bit
indicating the event.
Output mode
Setting the output mode selects the format in which the
counter will output measuring results to the controller. Se-
lect output mode by sending OUTM <number> where
<number> is a decimal value between 0 and 4 depending
on the selected output mode.

Default <number> is 0, when switching to local and back
again, the <number> will be reset to 0.
The MTCXO compensation can be switched off to in-
crease the measuring speed, providing a result with five
digits accuracy is sufficient. The time gained will be up to
400 ms/measurement.

Output format
Normal
When you select normal output format, the output will be
as follows:
Function command Header, 3-6 characters (same
Header as used for selecting the function).
O when overflow, otherwise space.
Measurement result, always 9 digits
and a decimal point. Same number of
significant digits as on the display of the
counter, leading zeroes fill out the rest
of the 9 positions. The leftmost digit
can be replaced by a (minus sign).
FFFFFFOXXXXXXXXXXE±XS(S)
EXAMPLE:
Normal operation:
PER 000001.667E–4
Overflow:
PER O9.99999999E+9
Short
Short format means that function command and leading
zeros are not sent to the controller. When you select short
output format, the number of digits may vary depending on
the measurement result. The example below shows a re-
sult with five significant digits:
Measurement result, same number of
digits as on the display of the counter;
may vary between 1 and 9 digits, plus
decimal point. No leading zeros are sent.
X.XXXXE ± XS(S)
EXAMPLE:
Normal operation:
1.667E–4
Overflow:
9.99999999E+9
High-speed Dump
The most time-consuming part of a measuring cycle is cal-
culating the result. The calculations limit the number of
possible results/second to about 5, even when the Measur-
ing-time is short.

Exponent sign, + or –.
Exponent, one digit.
