3-142. Blanks are inserted to make the message 17
bytes
long.
For example:
F +4.5834126E+5<CR/LF>
I I
17 characters
NOTE
There will be no decimal point in the string if it
occurs just before the E (this will occur only for
measurements with only one significant digit).
3-143. Numeric Entry
3-144. Numeric entry follows the code and format
guidelines of the IEEE 728 standard for NR3 numbers.
This
is a "free format" type of input, with spaces
allowed before a numeric entry begins, but not
afterwards. A decimal point is allowed anywhere in
the mantissa, but not required.
3-145. All local functions are programmable with
individual command codes via the interface. In
general, all
functions operate the same in remote as in
local. The counter commands are listed in Table 3-9,
Instrument Programming Command Set.
3-146. The examples at the end of this section de-
monstrate programming capabilities of the counter.
The examples are written for the HP-85A controller. A
summary
of the program operation and aline-by-line
description are provided for each example.
3-147. IN Initialize
3-148. This command causes the instrument to exit
its
current state and go to the power on initialize state
unless the instrument is in an error state. If the instru-
ment is in an error state, the error condition must be
cleared before the "IN" command is accepted. The
error may be cleared by pressing the blue reset key on
the front panel or by sending a DCL or SDC command
to the instrument.
3-149. WAO and WA1 Wait to Send Mode Off/On
3-150. The wait to send mode forces the instrument
to wait for a measurement to be read by the controller
before it can start a new measurement. This mode is
especially useful when used with service request. The
instrument will make a measurement and when the
measurement is complete, it will assert SRQ alerting
the controller to the fact that the measurement is
complete. This process ensures that the controller
knows when the measurement was made and that it
