1.10 Measuring AC voltages and AC currents
• AC signal ranges
The instrument accepts the measure of AC voltages and
currents, with ranges from 60 mVac up to 600 Vac, cov-
ering from shunt signals to typical power line voltages
of 48 Vac, 115 Vac, 230 Vac and even 380 Vac. Both
phase - to - neutral and phase - to - phase measures are accepted.
AC currents signals up to 5 Aac are accepted, and it has a range of
20 mAac.
•‘True RMS’ measure
AC measure are TrueRMS. The instrument assigns a ‘dead band’
around 0, with a congurable value between 0 and 100. Value is em-
pirical, and by default is set to 20. The ‘dead band’ can be congured
at the ‘Conguraon menu’ (see secon 1.29.7).
•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 1.25).
•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’ - External control
Terminal 5 remains congured as ‘EK’ external control funcon. See
secon 1.9 for a list of available funcons.
•Start-up, connecons and jumpers
For instrument start-up follow the steps listed at secon 1.7. Signal
connecons are indicated at secon 1.5. Locaon for internal jump-
ers is indicated at secon 1.9.

1.17 Measuring frequency
•How the instrument measures frequency
The instrument measures frequency from an AC voltage
(Vac) or AC current (Aac) signal. The instrument detects
each ‘0’ crossing of the signal, either ‘0 Vac’ or ‘0 Aac’. All
available Vac and Aac signal ranges are accepted as frequency input
signal.
•How to congure the instrument to measure frequency
To measure frequency from a Vac signal, select the internal jumpers for
the desired AC voltage range (see secon 1.9), connect the signal for
the selected voltage range (see secon 1.10), and congure the instru-
ment to measure frequency (see secon 1.29.1). The same applies to
measure frequency from Aac signals. See example at secon below.
• Scaling
The default resoluon is 0.1 Hz. 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 1.25).
•Maximum and minimum signal
Frequency signals below 15 Hz are measured as ‘0’. Frequency sig-
nals higher than 100 Hz are out of accuracy. Signals higher than
1000 Hz will read ‘display overow’ ‘d.oVr’ error.

•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 1.22).
•Scaling
The instrument allows to scale the reading to 4 digits (9999 / -1999)

The ‘fast access’ menu allows to congure the front key ‘UP’ (‘5’) as
a direct access to the alarm 1 and / or alarm 2 setpoint values, and / or
the memory of maximum and minimum reading. The objecve is to
provide the operator with a fast and direct access to alarm setpoints,
without accessing the standard conguraon menu.
Access to ‘fast access’ menu is sll allowed even with acve ‘pass-
word’ funcon, allowing the operator to modify the alarm setpoints,
while sll blocking any other change on the conguraon.
The ‘fast access’ menu is congurable, and it allows to assign to the
front key none, one, several or all of the available funcons. In case
of conguring access only to alarm 1, when pushing front key ‘UP’
(‘5’), the display directly access the setpoint value of alarm 1 (same
for alarm 2)
To congure the ‘fast access’ menu see secon 1.29.4.
1.21 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
Some examples are explained below:
• for AC voltage and current ranges, for example 0/600 Vac,
congure at ‘d.Lo’ the reading for a signal of 0 Vac. Congure at
‘d.Hi’ the reading for a signal of 600 Vac.
• for DC voltage and current ranges, for example ±600 Vdc, con-
gure at ‘d.Lo’ the reading for a signal of 0 Vdc. Congure at
‘d.Hi’ the reading for a signal of 600 Vdc.
• 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.
1.22 Oset reading
The instrument provides a ‘second scaling’, independent and addi-
onal to the standard scaling explained at secon 1.21. 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 1.29.6)
3. congure the scaling at the conguraon menu ‘Tools’ \ ‘ScL.2’
(see secon 1.29.7).
4. apply connecons to the external control
1.23 ‘Eco’ mode
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
• visualize de memory of maximum (or minimum)
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 1.29.6).
The funcon associated to the ‘EK’ external control acvates when
short-circuing terminal 5 and terminal 4.
1.24 External control
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, or when the opera-
tor touches any of the front keys. If no alarms are acve, and there
is no interacon from the operator, the instrument will turn o the
display. The waing me before display 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 1.29.7).
1.25 Second scaling
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 1.29.7).
* 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.

1.26 To open the instrument
To open the housing and access the internal circuits, use a at screw-
driver to unlock clips ‘D’, ‘C’, ‘B’ and ‘A’, in this order. Remove the
front lter. Let the inside of the instrument slide out of the housing.
To reinsert the instrument make sure that all modules are correctly
connected to the pins on the display module. Place all the set into
the housing, assuring that the modules correctly t into the internal
guiding slides of the housing. Once introduced, place again the front
lter at cover ‘X’, and then insert clips ‘A’, ‘B’, ‘C’ and ‘D’, in this order.
The internal structure of the instrument is shown in the graphic be-
low.
Module ‘Opt.2’ connects to module ‘Opt.1’. Module ‘Opt.1’ connects
to the display. Oponal modules can be replaced, changed, added or
removed simply by placing the proper module at the proper locaon.

The instrument has two menus accessible to the user :
‘Conguraon menu’ (key SQ) (<)
‘Fast access’ menu (key UP) (5)
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.
For a detailed explanaon on the ‘conguraon menu’ see secon
1.30, and for a full view of the ‘conguraon menu’ structure see
secon 1.30.
‘Fast access’ menu
The ‘fast access’ menu is an operator congurable menu, providing
fast and direct access to the most usual funcons of the instrument
with a single key pad stroke. Press key UP (5) to access this menu.
See secon 1.20 for a list of funcons eligible for ‘fast access’ in this
instrument. The ‘Password’ (‘PASS’) funcon does not block access
to this menu. Accessing and modifying parameters in the ‘fast access’
menu does not interfere with the normal funconality of the instru-
ment, and it does not generate any system reset when validang the
changes.

1.29 Conguraon menu
Press ‘SQ’ (<) for 1 second to access the ‘conguraon menu’.
For a descripon on how to operate inside the menus see secon
1.27. For a full vision of the ‘conguraon menu’ structure see
secon 1.30.
Access the ‘Input’ (‘InP’) menu to select the input signal range. For a
correct reading, the internal jumper ‘T’ (see secon 1.9) must also be
selected accordingly.
The instrument oers the following signal ranges :
• ‘AC signals’ (‘Ac’) - select a range between 600 Vac, 200 Vac,
20 Vac, 2 Vac, 200 mVac, 60 mVac, 5 Aac and 20 mAac. The AC mea-
sure ranges provide ‘True RMS’ reading.
• ‘DC signals’ (‘dc’) - select a range between ±600 Vdc, ±200 Vdc,
±20 Vdc, ±2 Vdc, ±200 mVdc, ±60 mVdc, ±5 Adc and ±20 mAdc. Dc
measures are bipolar.
• ‘Process’ (‘Proc’) - select 4/20 mA or 0/10 Vdc. The instrument
provides excitaon voltage to power up transducers at terminal 5.
To congure the excitaon voltage, see secon 1.16.
• ‘Thermocouples’ (‘tc’) - select the thermocouple type between
K, J, E, N, L, R, S, B, T and C. The instrument automacally compen-
sates for the thermocouple cold juncon.
• ‘RTD probes’ (‘rtd’) - the ‘rtd’ menu oers temperature resis-
ve probes type Pt (planum) and Ni (Nickel). Select the type of
probe from the available opons Pt100 3 wire, Pt100 2 wire, Pt500,
Pt1000, Ni100, Ni200 and Ni1000. For measures with 2 wires, a
manual compensaon for the wire resistance error is available us-
ing parameter ‘Oset reading’ (‘oFFS’) (see secon 1.22).
• ‘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 1.14.
• ‘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

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

The instrument has 2 independent and congurable alarms.
Control the independent acvaon of relays A1 installed (oponally)
at slots 1 and 2 (see secon 2.1) from menu entries ‘Alarm 1’ (‘ALr1’)
and ‘Alarm 2’ (‘ALr2’). Alarms control also the acvaon of front leds
‘1’ and ‘2’ located as indicated at secon 1.2.
To congure the alarms, enter at the alarm menu (‘ALr1’, or ‘ALr2’)
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. This parameter is eligible for conguraon through
the ‘Fast access’ menu (see secon 1.20).
• 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.

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-

• 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 1.25.
• 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 1.23. 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 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
(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 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 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 ‘Pass-
word’.
