The measured value is displayed as standard. At parameter setting, configuration, calibration level and at the extended operating level, the display changes cyclically between parameter name and parameter value.

After supply voltage switch-on, the unit starts with the operating level. The unit is in the condition which was active before power-off.

3.3.4 O2measurement
For measurement, lambda probes (l probes) are used. The electromotive force (in Volt) supplied by the l probes is dependent of the instantaneous oxygen content and of the temperature. Therefore, Digital 280-1 can display accurate measurement results only, provided that the probe tempera ture is known to the indicator. Enter the temperature in °C in parameter tEmP. When using heated l probes, the probe temperature can be entered directly. When using non-heated l probes, ho wever, the displayed values can be accurate only for a narrow temperature band.

Func r Fnc.1 3 O2 measurement
Display: The displayed value is always a % value. As it is mostly necessary to cover a wide measuring range, we recommend adju­sting a high number of digits behind the decimal point during configuration, whe­reby loss of high values is prevented due to floating decimal point display (0,0001 (1 ppm) to 99999 is possible) .
Specify the number of digits behind the decimal point below othr :
0 0 digits behind the decimal point 1 1 digit behind the decimal point

3.3.6 Alarm handling
Operation
Max. three alarms can be configured and assigned to the individual outputs. Ge nerally, outputs OuT.1... OuT.3 can be used each for alarm signalling. If more than one signal is linked to one output the signals are OR linked. Each of the 3 li mit values Lim.1 … Lim.3 has 2 trigger points H.x (Max) and L.x (Min), which can be switched off individually (parameter = “OFF”). Switching difference HYS.x of each limit value is adjustable.
