The trigger type and the limits of the range to be monitored may be specified using the trigger

range.
With the range trigger set to absolute values the incoming data are directly compared with the limits

values which have been set.

If "in" is selected then a trigger signal is generated if a value is recognised which is within the

limits set - including the limit values themselves.

If "out" is selected the signal has to be greater than the upper or smaller than the lower limit

value in order to activate a trigger.

After the measurement is started the respective input signal is monitored for the trigger conditions

which have been set and once such conditions occur and depending on the selection - start or stop

trigger - the state of the output signal switched over.

A TTL-compatible is signal value is issued for each incoming data value. For the start trigger this

value corresponds to the value TTL-low (numerical value 0) before occurrence of the trigger

conditions and the value TTL-high (numerical value 5) after occurrence of the trigger conditions. In

the case of the stop trigger the TTL-output level reacts in an exactly reverse fashion.

Perform the following steps:

1. Call up the parameter window by double-clicking the icon.
2. If necessary enter the

1DPH

of the trigger in the text field labelled ’Designation’.

3. Set range and type (Start / Stop Trigger, In / Out of Range) of trigger. Close parameter

window with

0XOWLSOH &KDQQHO 2SHUDWLRQ

For multiple channel operation the channels have to be identifiable in the results window. They are

capable of being marked.

Perform the following steps:

1. Set

&KDQQHO 1XPEHU

by clicking the upper arrow keys.

2. Select channel by clicking the lower arrow keys.
3. Enter

&KDQQHO 'HVLJQDWLRQ

into the text field, i.e. entry is made for each channel

selected.

4. Confirm with

The trigger control block may be used together with the

"relay" control block

in order to control

operations as a function of measured values.
