Fluke PM-3390B, PM-3380B, PM-3370B, PM-3394B, PM-3384B user manual BIT Decimal Meaning Number Value

COMMAND REFERENCE 4 - 91

The STATus:OPERation:PTRansition command sets the contents of the positive transition filter of the operation register structure. The positive transition filter specifies which bits in the operation condition register, that make a positive transition (0 -> 1), set the corresponding bit in the operation event register. For example, when you set bit 2 in this filter, it will set bit 2 in the operation event register at the time bit 2 in the operation condition register is set (changed from 0 to 1). After power, on the contents of the negative transition filter is set to #H7FFF.

The bits have the following value and meaning:

BIT	DECIMAL	MEANING:
NUMBER	VALUE
0	1	CALibrating (performing a calibration).
2	4	RANGing (currently autoranging, autosetting).
3	8	SWEeping (busy with acquisition).
5	32	Waiting for TRIGger (INITiated).
8	256	Instrument is in the digital mode.
9	512	Pass/Fail status (bit 10) is valid.
10	1024	Pass/Fail status; 1 = test has failed.
other		-------- Not used. Zero is returned --------

Example:

Send → STATus:OPERation:CONDition?

Requests for operational condition.

Read ← 4

The returned value 4 equals bit 2 set (instrument is currently autoranging).

Send → STATus:OPERation:ENABle 4

Enables report of bit 2 (RANGing) in operational event register.

Send → STATus:OPERation:NTRansition 0

Disables all bit reports from 1 to 0.

Send → STATus:OPERation:PTRansition 4

Enables report of "Autoranging started" (0 -> 1).

Send → STATus:OPERation:EVENt?

Requests for operational event.

Read ← 4

The returned value 4 equals bit 2 set (instrument has started autoranging).

Send → STATus:OPERation:PTRansition 0

Disables all bit reports from 0 to 1.

Send → STATus:OPERation:NTRansition 4

Enables report of "Autoranging stopped" (1 -> 0).

Send → STATus:OPERation:EVENt?

Requests for operational event.

Read ← 4

The returned value 4 equals bit 2 set (instrument has stopped autoranging).
