• the ‘ second scaling ’ ( ScL.2 ’) function allows to configure the
reading associated to the ‘second scaling’, which can be activated
by controlling a contact at the ‘external control’. For more infor -
mation on the ‘second scaling’ function see section
1.25.
• the ‘ Eco mode ’ (‘ Eco ’) is a function to reduce consumption of
the instrument, by powering off the display when display is not
needed. For consumption data in ‘Eco’ mode see section
1.8
. For
more information in ‘Eco’ mode see section
1.23.
The operation
of the ‘Eco’ mode is explained below :
- the waiting time until display is powered off display is con -
figurable from 5 to 255 seconds.
- after the configured time is over, without interaction from
the operator, the display powers off the reading. It will not
power off if the instrument is into ‘configuration menu’ or in
‘fast access’ menu or there is an active alarm.
- the instrument will power on the display when an alarm acti
-
vates (either alarm 1 or 2) and will remain on if alarm remains
active.
- the instrument will power on the display if the operator
press any front key.
• at the ‘ Temperature resolution ’ (‘ t.rES ’) menu select the reso -
lution to 1º or 0.1º. This resolution applies to temperature probes
Pt100, Pt500, Pt100, Ni100, Ni200, Ni1000, PTC and NTC. For
thermocouple probes resolution is fixed 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 pa -
rameter to ‘0.0385’ o ‘0.0390’. This parameter affects to Pt probes
(Pt100, Pt500, Pt1000) and it depends on the probe.
• at the ‘ Cold junction ’ (‘ cJc ’) menu select ‘on’ to activate the
thermocouple cold junction compensation. Select ‘off’ to deac -
tivate.
• the ‘ AC deadband ’ (‘ d.bnd ’) parameter applies only to AC mea -
suring 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 firmware version
installed on the instrument.
• at the ‘ Password ’ (‘ PASS ’) menu select a 4 digit code to block
access to the ‘ configuration menu ’. Use the ‘ Password ’ function
to prevent modifications on the instrument configuration. To ac -
tivate the ‘ Password ’ select ‘ on ’ and enter the numerical code.
The code will be requested when trying to access the ‘configura -
tion menu’. The ‘
fast access
’ menu is not blocked by the ‘ Pass-
word ’.
