taon voltage to power up transducers.
• Scaling
The instrument allows to scale the reading to 4 digits (9999 / -1999)
with congurable decimal point to any posion. The ‘second scaling’
funcon can also be used (see secon 1.21).
•Maximum oversignal
‘Maximum oversignal’ is the maximum signal accepted by the in-
strument. Higher signal values may cause instrument damage. Low-
er values are non destrucve but may be out of accuracy specica-
ons.
•Response mes
The response me to a signal step is 300 mSeconds, independent of
the signal range selected.
•Terminal 5 ‘mulfuncon’ - ‘Vexc’ or ‘External control’
To congure the +15 Vdc excitaon voltage at terminal 5, set internal
jumper ‘T’ at posion 1-2 (see secon 1.9). Transducers with a con-
sumpon of up to 30 mA can be powered from this terminal.

• Accepted NTC probes
The NTC probe is a temperature variable resistor with a
temperature - resistance curve dened by two param-
eters called ‘R25’ and ‘beta’. By default, the instrument
is congured for a standard NTC with ‘R25’ of 10K and
‘beta’ of 3500. The measured temperature ranges from -60 ºC to
150 ºC.
Dierent NTC probes can be used, by conguring the instrument for
dierent values of ‘R25’ and ‘beta’. The instrument measures resis-
tance from 100 R up to 1 MOhm. Use ‘Table 7’ to write down values
for your NTC.
• Parameters ‘R25’ and ‘Beta’
The instrument accepts values of ‘beta’ between 2500 and 5500, and
values of R25 between 1.0 K and 200.0 K
• Resoluon and units
The temperature resoluon using NTC temperature probes is con-
gurable to 1º or 0.1º. Reading can be congured in ºC (degrees Cel-
sius) or ºF (degrees Fahrenheit).

• Measuring resisve signals
The instrument accepts the measure of resistances and
provides two ranges of measure from 0 to 5 K and from
0 to 50 K.
•Compensang the resistance of the signal wire
Resistances are measured with 2 wires system. To compensate for
the possible error introduced by the resistance of the signal wires,
the instrument allows to congure a xed number of counts to be
added to the reading, both in posive or negave. This is done with
the parameter ‘Oset reading’ (‘oFFS’) (see secon 1.18).
•Scaling
The instrument allows to scale the reading to 4 digits (9999 / -1999)
with congurable decimal point to any posion. The ‘second scaling’
funcon can also be used (see secon 1.21).

1.17 Scaling
The instrument can scale the reading to any value between 9999 and
-1999 and congure the decimal point posion, for all signal ranges
except temperature ranges (thermocouples, Ni and Pt sensors, NTC
and PTC sensors) are not scalable. The scaling conguraon is a sim-
plied two steps process :
1. congure at the ‘Display Low’ (‘d.Lo’) parameter the reading
value associated to the low signal range
2. congure at the ‘Display High’ (‘d.Hi’) parameter the reading
value for the high signal range
Two examples are explained below:
• for process ranges, for example 4/20 mA, congure at ‘d.Lo’
the reading for a signal of 4 mA. Congure at ‘d.Hi’ the reading
for a signal of 20 mA.
• for potenometer ranges, congure at ‘d.Lo’ the reading for a
signal of 0% (0 R). Congure at ‘d.Hi’ the reading for a signal of
100% (nominal of the potenometer).
To congure the scaling see secon 1.29.2.
The ‘external control’ funcon allows to acvate, by closing a free
potenal contact, one of the following congurable funcons :
• acvaon of the second scaling
• change the acve decimal point
• ‘hold’ the reading
• ‘tare’ funcon
To congure the ‘EK’ external contact funcon, set internal jumper
‘T’ at posion 4-5 (see secon 1.9). The ‘EK’ external control funcon
is not compable with funcon ‘Vexc’ (excitaon voltage), the mea-
sure of 3 wire Pt100, and the measure of potenometers.
To assign a funcon to the ‘external control’ see the conguraon
menu at ‘External control’ (see secon 1.29.4).
The funcon associated to the ‘EK’ external control acvates when
short-circuing terminal 5 and terminal 4.
1.20 External control
1.19 ‘Eco’ mode
The ‘Eco’ mode reduces the consumpon of the instrument to a level
of 0.3 W. The ‘Eco’ mode turns o the display, while the right decimal
point remains ashing gently on and o, showing that the instrument
is running on the background.
Display will turn on when an alarm acvates. If no alarms are acve,
the instrument will turn o the display. The waing me before dis-
play turn o is congurable from 5 to 255 seconds.
To congure the ‘Eco’ mode see the conguraon menu at ‘Tools’ \
‘Eco’ (see secon 1.29.5).
The instrument provides a ‘second scaling’, independent and addi-
onal to the standard scaling explained at secon 1.17. Control of
the scaling to be applied, with a free potenal contact called ‘Exter-
nal control’. To congure the ‘second scaling’ :
1. congure the internal jumper ‘T’ to acvate the ‘EK’ external
control funcon (see secon 1.9).
2. associate the external control to the ‘second scaling’ funcon,
at the conguraon menu ‘ScL.2’ set the value ‘EXt.c’ (‘External
control’) (see secon 1.29.4)
3. congure the scaling at the conguraon menu ‘Tools’ \ ‘ScL.2’
(see secon 1.29.5).
4. apply connecons to the external control
1.21 Second scaling1.18 Oset reading
The ‘Oset reading’ (‘oFFS’) parameter allows a number of counts
to be subtracted from the reading. This is specially useful to manu-
ally compensate for resistance errors due to wire resistance, when
measuring with 2 wires Ni and Pt probes, and resistances. Applies
to all signal ranges. See conguraon menu at ‘Tools’ \ ‘oFFS’ (see
secon 1.29.5).
* Risk of electric shock. The ‘EK’ external control funcon shares termi-
nal 4 with the common of the input signal connecon. When measur-
ing dangerous voltages AND using ‘EK’ external control contact, apply
the appropriate protecons to isolate the operator from dangerous voltages.

Conguraon menu
The ‘conguraon menu’ modies the conguraon parameters to
adapt the instrument to the applicaon needs. To access the ‘con-
guraon menu’ press for 1 second the SQ (<) key. This access can
be blocked by acvang the ‘Password’ (‘PASS’) funcon. While
operang the ‘conguraon menu’, the alarm status is ‘hold’ to the
status they had before accessing the menu, and the output and con-
trol modules remain in ‘error’ state. When leaving the ‘conguraon
menu’, the instrument applies a system reset, followed by a brief
disconnecon of the alarms and the output and control modules.
Funconality is then recovered.

• ‘NTC probes’ (‘ntc’) - select the ‘ntc’ menu to congure the input
for NTC probes. To correctly congure the measure for NTC, two pa-
rameters need to be dened : rst the resistance of the NTC probe
at 25º (‘r.25’) and parameter ‘beta’ (‘bEtA’). The instrument accepts
beta values between 2000 and 5500, and values of R25 between
1.0 K and 200.0 K. For more informaon on NTC measures see sec-
on 1.13.
• ‘PTC probes’ (‘Ptc’) - select the ‘ptc’ menu to congure the input
for PTC probes. Select K121 for PTC probes from the KTY-121 family
(KTY81-121 and KTY82-121). Select K220 for PTC probes from the
KTY-210 family (KTY81-210 and KTY82-210) and KTY-220 (KTY81-
220 and KTY82-220). For more informaon on PTC probes see sec-
on 1.14.
• ‘Resistance’ (‘rES’) - select 5 K for a measuring range from 0 to
5 KOhms or select 50 K for a measuring range of 0 to 50 KOhms.
For a manual compensaon for the error introduced by the signal
wires, see parameter ‘Oset reading’ (‘oFFS’) (see secon 1.18).
• ‘Potenometer’ (‘Pot’) - potenometer measure has a single
range, valid for any potenometer with nominal value between
500 R and 20 K.

1.29 Conguraon menu (cont.)
Scale the reading at the ‘Scaling’ (‘ScAL’) menu. Temperature ranges
(thermocouples, Pt and Ni probes, NTC and PTC probes) have direct
temperature indicaon and are not scalable.
To congure the scaling, enter the ‘Decimal point’ (‘dP’) parameter
and select the desired posion for the decimal point, using key ‘LE’
(3).
Then congure at the ‘Display Low’ (‘d.Lo’) parameter the reading
value associated to the low signal range and congure at the ‘Display
High’ (‘d.Hi’) parameter the reading value for the high signal range.
For more informaon see secon 1.17.
1.29.2 Scaling
To congure the alarms, access the alarm menu (‘ALr.1’ or ‘ALr.2’)
and congure the following parameters.
• at the ‘Alarm type’ (‘TypE’) parameter select alarm as as a max-
imum type alarm (‘MAX’) or a minimum type alarm (‘MIn’). The
maximum type alarm (or minimum type) acvates when the dis-
play value is higher (or lower) than the setpoint value.
• at the ‘Setpoint’ (‘SEt’) parameter enter the value for the alarm
acvaon point.
• congure the hysteresis value at ‘Hysteresis’ (‘hySt’). The hys-
teresis applies to the deacvaon process of the alarm. The alarm
deacvates when the reading has passed the setpoint value plus
the hysteresis value. Hysteresis helps to avoid repeve switching
of the alarm relays, due to uctuang input signals around the set-
point.
• at the ‘Flash’ (‘FLSh’) parameter select ‘on’ to acvate the reading
in ashing mode when the alarm is acve.

An external on / o control can be connected to the rear of the in-
strument. The operator can then control the acvaon of a cong-
ured funcon based on the state of this control. Funcon remains ac-
vated while the external contact is closed, and will deacvate when
contact is open. To congure the funcon associated to the external
control, enter the menu ‘External control’ (‘EXt.c’).
• select ‘Disabled’ (‘oFF’) to have no funcon associated.
• select parameter ‘Display hold’ (‘hoLd’) to maintain the actual
reading ‘on hold’. Open the external contact to free the reading.
While ‘hold’ funcon is acve, the reading will be shown in ash
mode, indicang that the actual value is not the actual input value.
• select ‘Tare funcon’ (‘tArE’) to acvate a tare to the signal. The
actual signal will read ‘0’. The calibraon is not changed.

1.29 Conguraon menu (cont.)
The ‘Tools’ (‘tooL’) menu contains mulple conguraon opons of
the instrument.
• the ‘Steps’ (‘StEP’) parameter allows to congure a dened
minimum step change on the reading. Reading will change in
steps of 1, 2, 5, 10, 20 or 50 counts.
• the ‘Average lter’ (‘AVr’) funcon allows to reduce reading
oscillaons due to noisy signals, by applying a recursive lter on
the reading values. The strength of the recursive lter is a value
congurable between ‘0’ and ‘100’. Value ‘0’ means ‘lter dis-
abled’. Filter strength increases with the value. Increasing the l-
ter strength, increases the response me of the instrument.
• the ‘Oset reading’ (‘oFFS’) parameter allows to congure a
xed number of counts to be subtracted from the reading. Ac-
cepts values from -500 to 500. This funcon allows to compen-
sate for the possible error introduced by the resistance of the
signal wires when measuring Pt probes, Ni probes or resistances.
For more informaon see secon 1.18
• 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 infor-
maon on the ‘second scaling’ funcon see secon 1.21.

• select parameter ‘Decimal point 0’ (‘dP.0’) to remove the decimal
point on display.
• select parameter ‘Decimal point 1’ (‘dP.1’) to acvate the decimal
point at posion XXX.X
Parameters ‘Decimal point 0’ (‘dP.0’)and similar ‘dP.1’, ‘dP.2’ and
dP.3’ control which decimal point is on. When the external contact
closes, the decimal point selected lights on and the decimal point
that was acvated before will power o. When the external contact
opens, the previous decimal point powers on again while removing
the new decimal point. Display does not show in ash mode when
decimal point funcons are acvated.
• select parameter ‘Second scaling’ (‘ScL.2’) to acvate the second
scaling congured at menu ‘Tools’ (‘TooL’) \ ‘Second scaling’. The
acvaon of the ‘Second scaling’ funcon is accepted for all signal
input ranges based on AC input signals, DC input signals, process
and resistances. Display does not show in ash mode when second
scaling funcon is acvated. For more informaon on the ‘Second

• 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 1.19. 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
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.
• at the ‘Temperature resoluon’ (‘t.rES’) menu select the reso-
lu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 pa-
rameter to ‘0.0385’ o ‘0.0390’. This parameter aects to Pt probes
