USET, USET? – Voltage Setpoint Value
Function and manual operation:
See explanation on page 20.
Programming
Setting command: USET v
Parameter: v (value)
Parameter type: Real number
Setting range: 0  v  ULIM
Default setting: After RESET (*RST)  0.00 V
Example (HP BASIC):
OUTPUT 713;"USET 12.5"
{voltage setpoint: 12.5 V}
Comments
 USET cannot be set to a value of greater than ULIM.
 Any setting command to this effect is not executed.
 Bit 1 would otherwise be set in event register B (limit error), and
bit 4 in the standard event register (execution error).
 If the selected value is not a whole number multiple of the step
size, it is rounded off accordingly.
 If necessary, the numeric value is rounded off once again for
the 4-place digital display.
Query
Also displays the output voltage setpoint defined by means of
USET.
Programming
Query command: USET?
Response string: USET v
Length: 13 characters, fixed
Parameter v (value)
Format v: +nnn.nnn
Example (HP Basic):
OUTPUT 713;"USET?"
ENTER 713; A$
DISP A$
Display: USET +012.500
WAIT – Additional Waiting Time
Function:
Additional waiting time between execution of two commands.
This function can be used to add additional waiting time within a
command string (linked commands) during processing /
execution.
For example, this allows for defined programming of a specified
power-on status / start-up edge within a command string with
execution time in the millisecond range.
Programming
Setting command: WAIT v
Parameter: v (value)
Parameter type: Real number
Setting range: 0.001 <s>  v  9.999 <s>,
resolution: 1 ms
Comments
The length of the command string may not exceed 255
characters (= buffer length), because an unspecified pause would
otherwise occur as a result of the additional data transmission.
Attention:
Data are not processed during waiting time, and the input buffer
is disabled, which means that the display messages are not
updated during this time either.
Example
"USET 0; ISET 5; OUTPUT ON; WAIT 0.001; USET 3; WAIT
0.003; USET 7; WAIT 0.003; USET 10"
(or "US 0; IS 5; OU ON; W .001; US 3; W .003; US 7; W .003; US
10" with decoupled command name)
