User manual for meter with thermocouple input PAC-73T Figure 6.1. Process of peaks detection 6.3. CONTROL OF THE RELAY OUTPUTS The control of the object (measured signal) is realized via relay outputs. Front panel LEDs named “R” indicates the state of particular relay output. If device is not equipped with one or more relay outputs, menus refer to this relays are available, but apply to LED indicators only. - Page 16 User manual for meter with thermocouple input PAC-73T Figure 6.2. One threshold control of the relay/LED outputs Figure 6.3. Two thresholds control of the relay/LED outputs The relay outputs and LEDs (named R) can be controlled depend on both - the current value and the peak value (when peak detection is active) of the input signal.
