Programming —DM 5010
COMMANDS
The instrument is controlled by the front panel or via
commands received from the controller. These commands
are of three types:
Setting commands— control instrument settings.
Query-output commands — ask for data.
Operational commands— cause a particular action.
The instrument responds to and executes all commands
when in the remote state. When in the local state, setting
and operational commands generate errors since instru­
ment functions are under front panel control; only query­
output commands are executed.
Each command begins with a header —a word that de­
scribes the function implemented. Many commands require
an argument following the header— a word or number that
specifies the desired state for the function.
Using fewer characters than the abbreviated header
or argument should be done with caution since erro­
neous results or damage could result if this data is
sent to the wrong instrument.
> CAUTION <
With the instrument in the AUTO range mode, do not
repeatedly switch the input voltage between a low val­
ue (<200 mV peak) and a higher value (>200 V
peak). For repeated measurements alternating be­
tween these voltage extremes, use the STEP range
mode to select an appropriate higher range before in­
creasing the input voltage. Failure to do so may tem­
porarily cause inaccuracy in measurements made
using the 200 mV range.
