*TRG

TRIGGER

Table 4-5. Command and Query Reference (cont)

Totalizer Value Query

Returns the value of the present Totalizer count. Format of the value is +00.000E+3. When the Totalizer has overflowed, the value returned is +001.00E+9.

Example: TOTAL? returns 13.465E+3 [The present value of the totalizer count is 13,465.]

Set Totalizing Debounce

Set totalizing input debounce state, which adds a delay of 1.75 ms to each transition, allowing increased accuracy from totalizer inputs from contact closures.

TOTAL_DBNC

<dbnc_state>

 

 

<dbnc_state>

= 1 (on) 0 (off)

Use of any other value causes an Execution Error to be generated. At initial power up, totalize debounce is disabled (0). An Execution Error is generated if the totalizer debouhce setting is changed when scanning while logging to the memory card is enabled.

Totalizer Debounce Query

Returns the totalizing input’s debounce state, as selected with the TOTAL_DBNC command.

0Debounce is off

1Debounce is on SIngle-Scan Trigger

(See front of table.)

Select Trigger Type

Select the type of scan triggering option. The use of a trigger option has the same effect as pressing the front panel Qkey. An input for an external trigger is available at the ALARM OUTPUTS connector on the rear panel of the instrument, pins TR and GROUND (TRIGGER 1). Scanning can also be enabled when a monitored channel goes into alarm (TRIGGER 2).

TRIGGER 0 External trigger and Alarm trigger disabled

TRIGGER 1 External trigger enabled

TRIGGER 2 Alarm trigger enabled

TRIGGER 0 means external triggering is disabled and only normal scan interval triggering can be used. If this command is entered during scanning while logging to the memory card, an Execution Error is generated.

TRIGGER 1 means that external triggering is enabled. An acceptable low input (-0.6 to +0.8V dc) between the pins TR and GROUND on the ALARM OUTPUTS connector on the rear panel will cause the instrument to start scanning. When the TR input returns to logic high, scanning is disabled. External trigger inputs during a scan are ignored.

TRIGGER 2 means the alarm trigger is enabled. When a channel being monitored goes into alarm, the instrument starts scanning. When the channel being monitored goes out of alarm, the instrument stops scanning. The *TRG and GET commands can be used with a trigger option selection.

If the trigger type given is not one of the listed values, an Execution Error is generated.
