Table 4-8. Command and Query Reference (cont)
TOTAL Set Totalizer Count
Give the Totalizer count a new initial value.
TOTAL <t_value>
<t_value> = (0 .. 65535)
If the value is not in the range 0 through 65,535, an Execution Error is
generated.
Clear the Totalizer count by setting the Totalizer to zero (0).
TOTAL? 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.
TOTAL_DBNC Set Totalizing Debounce
Set totalizing input debounce state.
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).
TOTAL_DBNC? Totalizer Debounce Query
Returns the totalizing input’s debounce state as an integer. When
disabled, the response is 0, indicating debounce is not in use. When
enabled, the response is 1, indicating debounce is being used.
TRIGGER Select Trigger Type
Select the type of scan triggering.
TRIGGER <trig_type>
<trig_type> = 0 (off) 1 (on) 2 (alarm)
Off (0) signifies that external triggering is disabled. Only normal scan
interval triggering can be used. If the scan interval is 0, continuous
scanning results. On (1) means that external triggering is enabled. An
acceptable low input on the External Trigger input (TR terminal on the rear
panel) then affects scanning as follows:
If the instrument is in Inactive Mode or Monitor Mode, the low input
enables scanning. When the TR input returns to high, scanning is
disabled.
If scanning is already enabled, the external trigger requests a single scan.
This request is ignored if a scan is presently in progress.
Alarm (2) signifies that an alarm condition on the monitor channel triggers
a single scan. When the scan is completed, the Monitor function is
resumed. This cycle repeats as long as the alarm condition is encountered
on the monitor channel. The external trigger input is disabled. The *TRG
and GET commands can still be used.
If the type given is not one of the listed values, an Execution Error is
generated.
