• the ‘second scaling’ (ScL.2’) funcon allows to congure the
reading associated to the ‘second scaling’, which can be acvated
by controlling a contact at the ‘external control’. For more
informaon on the ‘second scaling’ funcon see secon 1.24.
• the ‘Eco mode’ (‘Eco’) is a funcon to reduce consumpon of
the instrument, by powering o the display when display is not
needed. For consumpon data in ‘Eco’ mode see secon 1.8. For
more informaon in ‘Eco’ mode see secon 1.22. The operaon
of the ‘Eco’ mode is explained below :
- the waing me unl display is powered o display is
congurable from 5 to 255 seconds.
- aer the congured me is over, without interacon from
the operator, the display powers o the reading. It will not
power o if the instrument is into ‘conguraon menu’ or in
‘fast access’ menu or there is an acve alarm.
- the instrument will power on the display when an alarm
acvates (either alarm 1 or 2) and will remain on if alarm
remains acve.
- the instrument will power on the display if the operator
press any front key.
• at the ‘Temperature resoluon’ (‘t.rES’) menu select the
resoluon to 1º or 0.1º. This resoluon applies to temperature
probes Pt100, Pt500, Pt100, Ni100, Ni200, Ni1000, PTC and NTC.
For thermocouple probes resoluon is xed to 1º.
• at the ‘Degrees’ (‘dEG’) menu select the temperature values to
be read in ºC (degrees Celsius) or in ºF (degrees Fahrenheit).
• at the ‘Alpha’ (‘ALPh’) menu select the value for the alpha
parameter to ‘0.0385’ o ‘0.0390’. This parameter aects to Pt
probes (Pt100, Pt500, Pt1000) and it depends on the probe.
• at the ‘Cold juncon’ (‘cJc’) menu select ‘on’ to acvate the
thermocouple cold juncon compensaon. Select ‘o’ to
deacvate.
• the ‘AC deadband’ (‘d.bnd’) parameter applies only to
AC measuring ranges. The True RMS measures deal with a
considerable noise when signal is near to 0. This parameter allows
to set a value between 0 and 100 (by default is 20) to empirically
set the signal level at which reading will be forced to 0, when
signal is below that level.
• at the ‘Brightness’ (‘LIGh’) menu select between 5 levels of
brightness intensity for the display. It adapts the instrument to
environments with higher or lower brightness is needed or to
adapt the intensity to other meters in the area.
• the ‘Version’ (‘VEr’) menu informs about the rmware version
installed on the instrument.
• at the ‘Password’ (‘PASS’) menu select a 4 digit code to block
access to the ‘conguraon menu’. Use the ‘Password’ funcon
to prevent modicaons on the instrument conguraon. To
acvate the ‘Password’ select ‘on’ and enter the numerical code.
The code will be requested when trying to access the ‘conguraon
menu’. The ‘fast access’ menu is not blocked by the ‘Password’.
• At the ‘Factory reset’ (‘FAct’) menu, select ‘yes’ to load the
