PRODUCT DESCRIPTION

The MSC calibrator is a portable multi-function instrument for the
generation and measurement of signals commonly found in auto­mation environments.
It was designed to help professionals who have to verify and de­velop signal processing equipment connected to automatic control
devices.
Unlike what the market offers, the MSC calibrator combines
simulations and measurements in one instrument using the user’s
smartphone, tablet or Windows PC (via the USB cable) for an
intuitive and modern interface.

The MSC multifunction process calibrator is a hand-held instru­ment, powered by rechargeable batteries, used to measure and
generate electrical quantities.
In addition to the functions described in the "FUNCTIONS" para­graph (page 15), the calibrator has the following characteristics:

• Input/output terminal for thermocouples (TC) and isothermal
internal block with automatic temperature compensation of the
reference junction.

• 4 standard 4mm diameter bushings for 2-3-4 wire sizes.

• Protection against overvoltages up to 250 Vac.

• Lithium battery power supply, with up to 14h autonomy.

• Bluetooth connection with tablet and smartphone.

• Management of universal signals (analogue, digital, pulse,
electrical, weight, temperature)

• High accuracy class: 0.05% basic class for each type of input/
output.

• Data always available thanks to the dedicated app.

6 MI004962-E MSC

• Micro USB connector for power supply and PC connection.

The analogue signals managed both in measurement and genera­tion are:

• Milliamperes (dc)

• Volts, millivolts (dc)

• Thermocouples, two/three or four-wire heating elements

• 350 Ω bridge extensometer (LOAD CELL)

The following are also managed:

• Pulse generation with duration, voltage amplitude and variable
duty cycle

• Pulse measurement with adjustable threshold

• Frequency measurement and generation

The device is protected against damage due to incorrect connec­tions such as short circuits and overvoltages applied to the inputs
(e.g. 230 Vac).
The simplicity of use of the connections and the protections against

overload make the device suitable even for the less experienced

and in a hobby and educational environment.
It is possible to connect multiple calibrators to a smartphone and
control them individually.

11MI004962-EMSC

USER GUIDE

The calibrator is a device that can measure or generate electrical
quantities to test devices.
To proceed with the correct use of the instrument, make sure to
follow the following steps:

• Turn on the device and connect with the APP via Bluetooth.

• Wait 5 minutes for the appliance temperature to stabilize.

• Connect the cables correctly, according to the type of meas­urement/generation to be carried out: refer to the connection
diagrams on p. 36.

It is however necessary, before use, to make sure that the battery
is fully charged so as to guarantee its life for the generations or
measurements that will be carried out. Before each use it is advis­able to recharge the instrument using the USB cable supplied, until

the LED battery charge indicator on the bottom of the calibrator

goes off, as shown in the diagram on page 9.
The calibrator can maintain the signals to be generated (set by the
user) within a determined error range.
During generation, the calibrator will constantly check the generat­ed signal, warning about any generation error (where provided for)

by notifying it on the APP.

CAUTION

The calibrator is protected against the risk of applying temporary
overvoltages. However, it is good to remember that in this case the
device needs 15-20 minutes to restore the normal conditions.
If this period of time is not observed, the accuracy of the measure­ments and/or generations cannot be guaranteed.

12 MI004962-E MSC

Be careful when using the calibrator with devices that have earth

connections. Connections 1 and 2, shown in FIG. 1, can exist, but

not simultaneously.
This working condition can interfere with the correct operation of
the calibrator and the Bluetooth connection.
If this connection is made during the generation of an electrical
quantity, internal protections may intervene, in which case, once
the correct electrical connection between the devices has been
restored, it is necessary to leave the calibrator inactive for about
15-20 minutes to go back to normal conditions.

In order to achieve proper PC//measurement systems (EUT)

isolation and to protect the USB port of your PC, you must use the
USB-ISO accessory as shown in Fig. 2.

MEASUREMENTS

Checks common to all measurements

The following are the checks that are common to all measure­ments:

Sample screen from the APP:

The images and diagrams shown must be considered as indicative and not binding

since they are subject to possible updates.

16 MI004962-E MSC

In the sample screen it is possible to distinguish the checks that
are common to all the measurements (red) and those common to
analogue measurements (orange) only.
In red you can identify the checks that have the following mean­ings:

• Zeroing of MIN / AVG / MAX measurements, for analogue

measurements

• Count zeroing for pulse measurement

• Pausing of analogue or digital measurements

• Sharing the measurements taken. This button allows for exam­ple sharing a memo of the measurements just made.

• Datalogger: the activation of this function allows starting to
record the measurements that are being taken.

The MIN / AVG / MAX measurements are identied in orange and

the check allows changing the display from primary to second­ary measurement and vice versa.

17MI004962-EMSC

CURRENT / VOLTAGE MEASUREMENTS

The calibrator can measure voltages and currents that are applied
to the two innermost bushings (SN+ SN-) according to the following
ranges.

For the voltages, two measurement scales are available:

• Voltage -10÷90 mV ( LowRange)

• Voltage 0÷27 V ( HiRange)

To carry out the voltage measurement, connect the calibrator
according to gures M5 or M7 while, to make a current measure­ment, connect the calibrator according to FIG. M1 or M3 (page 36).

Once the calibrator is connected and the Bluetooth connection is

working, press M (Measurement) on the Home screen of the APP
and select "CURRENT / VOLTAGE".

Then select the desired size.
Since the measurements are homogeneous in the way they are

presented by the APP, a measurement is then taken into considera­tion; then choose "VOLTAGE 0.27 V".

The calibrator starts displaying the values related to the voltage
applied to the input bushings in Volts. The default value displayed
is in Volts. The measurement can be displayed as a percentage of
the full scale by pressing the P9 button (double arrow symbol)

If the measurement is unstable, ltering can be applied. To activate

it, follow the following steps by pressing:

1. Settings (refer to image on page 47)

2. AVG lter settings

Then select the desired ltering time between: 0.25, 0.5, 1, 2, 4, 8

seconds.

18 MI004962-E MSC

FREQUENCY MEASUREMENTS

The calibrator allows the measurement of the voltage pulses
applied in the two innermost bushings (SN+ SN-). The electrical
connections are shown in FIG. M8

Once the calibrator is connected and the Bluetooth connection

works, press M (Measurement) on the APP Home screen and then
choose "FREQUENCY"

To correctly detect a frequency of a voltage signal applied to the
bushings, it is important to choose an appropriate trigger threshold
by going to:

1 Settings
2 Set trigger level

The calibrator shows the frequency in Hz.

19MI004962-EMSC

THERMOCOUPLE MEASUREMENTS

The calibrator allows the temperature measurement with thermo­couples which are connected via connector 1 (diagram on page 9).
The electrical connections are shown in FIG. M2 (page 36).

For the types of supported thermocouples, refer to TAB 1 (page

50).

Once the calibrator is connected and the Bluetooth connection

works, press M (Measurement) on the APP Home screen and then
choose "THERMOCOUPLE". Then select the type of thermocouple

you wish to take the measurement with.

In measurement mode the temperature value in °C (and mV) is
shown. The displayed temperature value is the real temperature
measured by the thermocouple, including the cold junction com-

pensation (depending on the set conguration). This last value is

shown on the display with the wording
“C.J. Read”.
On the other hand, the value in mV is the real voltage value read
by the terminals without any compensation.

If the measurement is unstable, ltering can be applied.

To activate it, follow the following steps by pressing:

1. Settings

2. AVG lter settings

Then select the desired ltering time between: 0.25, 0.5, 1, 2, 4, 8

seconds.

20 MI004962-E MSC

CAUTION

Wait until the device reaches a stable thermal condition before
taking measurements with the thermocouples (typically at least 30
minutes).

CAUTION

If the thermocouple does not have its own connector, use the inner­most bushings SN+ SN- as an alternative, bearing in mind that the
compensation of the cold junction in this case may be less precise.

21MI004962-EMSC

RESISTANCE THERMOMETER MEASUREMENTS (RTD)

The calibrator allows the measurement of the temperature with
resistance thermometers connected with 2, 3 or 4 wires that are
connected to the bushings, according to the types indicated in

TAB 1 (page 50). The electrical connections are shown in FIG. M4

(page 36).

Once the calibrator is connected and the Bluetooth connection

works, press M (Measurement) on the APP Home screen and then

choose "RTD". Then select the type of resistance thermometer you
want to measure.

In RTD measurement mode, the temperature value in °C is shown
according to the type of resistance thermometer selected, along

with the value measured in Ω.

If the measurement is unstable, ltering can be applied. To activate

it, follow the following steps by pressing:

1. Settings

2. AVG lter settings

Then select the desired ltering time between: 0.25, 0.5, 1, 2, 4, 8

seconds.

22 MI004962-E MSC

PULSE MEASUREMENTS

The calibrator allows the measurement of the voltage pulses
applied in the two innermost bushings (SN+ SN-). The electrical
connections are shown in FIG. M8 (page 37).
Once the calibrator is connected and the Bluetooth connection

works, press M (Measurement) on the APP Home screen and then
choose "PULSE" followed by the mode in which the pulse is to be
detected: "POSITIVE FRONT SIGNAL WITH PULSES" or "NEG­ATIVE FRONT SIGNAL WITH PULSES" (the pulse is detected on

the rising or falling edge when crossing the set trigger threshold)

To correctly detect the pulses it is important to choose an appropri­ate trigger threshold by going to:

1. Settings

2. Set trigger level

It is possible to lter the pulses applied to the input bushings by ap­plying the pulse minimum duration lter. The pulse is then detected

only if its duration is greater than or equal to the set value.

To change this parameter follow the following steps:

1. Settings

2. Set minimum pulse duration

then set the value expressing it in micro seconds.

23MI004962-EMSC

MEASUREMENTS WITH LOAD CELLS

The calibrator is compatible with load cells having a rated resist-

ance of 350 Ω.

Be sure to follow the guidelines for use to take measurements
correctly.

By activating this measurement function, the device supplies the
load cell through the outermost terminals (+EX -EX) while the gen­erated signal is read via the innermost terminals (+SN -SN)

To take the measurement, connect the calibrator according to g.

M6 (page 37); on the Home screen, press M (Measurement) and
then "Load Cell".
The measurement of the load cell is displayed in two ways:

• mV/V ratio

• weight in Kg

To set the sensitivity of the load cell sensor or set the tare and full

scale in Kg press:

1. Settings

2. Options

In the "load cell settings" screen you can:

• Set the unit of measurement

• Set cell sensitivity [mV/V]

• Set the load cell capacity [Kg]

• Zero the tare: before proceeding to zero the tare, make sure

24 MI004962-E MSC

that the measurement on the display is stable then proceed with
resetting using the reset button:

TARE

If the measurement is unstable, ltering can be applied. To activate

it, follow the following steps by pressing:

3. Settings

4. AVG lter settings

Then select the desired ltering time between: 0.25, 0.5, 1, 2, 4, 8

seconds.

CAUTION

The 4-wire measurement of the load cell is inuenced by the resist­ance of the conductors supplying it. If it is not possible to shorten
the connections between the load cell and the MSC calibrator, by
measuring the resistance only of the conductors that supply the

350+R

K=

+EX +R-EX

350

load cell (conductors +EX and -EX), the correction coefcient can

be calculated:
The obtained coefcient must be multiplied with the value meas­ured by the calibrator to obtain the real value.

25MI004962-EMSC

GENERATION / SIMULATION

The following are the checks that are common to all measure­ments:

APP sample screen:

The images and diagrams shown must be considered as indicative and not binding

since they are subject to possible updates.

26 MI004962-E MSC

In the sample screen, a distinction is made between the checks
common to all analogue generations (in orange) and those of the
pulse generation only (in red).

In Orange it is possible to identify the area where the generation
value can be set by using the up/down swipe and the keyboard to
enter the desired value. The other checks are listed below:

• Button indicating the status of the generation (active or not).
Pressing it, the output is deactivated and the button changes
status.

• Command to reverse the primary and secondary measure­ments and vice versa

• Ramp function start button.

In red we can identify the elements that concern the generation of

pulses; in the example we can identify the 8 remaining pulses to be

generated and the three buttons:

• START: starts the generation of voltage pulses

• PAUSE: temporarily interrupts the generation of pulses

• STOP: cancels the current pulse generation session

27MI004962-EMSC

CURRENT / VOLTAGE GENERATION

The calibrator can operate as a voltage or current generator. These
quantities are supplied by the innermost bushings (SN+ SN-)
according to the following ranges.
For the voltages two generation scales are available:

• Voltage -10÷90 mV

• Voltage 0÷27 V

To carry out voltage generation, connect the calibrator according

to gure G7 (page 39), while to generate a current, connect the
calibrator according to gures G1 or G3 (page 38) depending on

whether you want to generate a passive or active current.

Once the calibrator is connected and the Bluetooth connection

works, press G (signal Generator) on the APP Home screen and
choose "CURRENT / VOLTAGE".

Then select the desired voltage or current generation.

Since the generations are homogeneous in the way they are

presented by the APP, the following shows a sample generation.
Select "VOLTAGE 0.27 V".

The generation screen is displayed and the calibrator starts supply­ing the output bushings with the preset voltage of 0 V. To change
this value, simply enter the desired value using the numeric keypad

and conrm with OK.

28 MI004962-E MSC

THERMOCOUPLE SIMULATION

The calibrator can simulate a thermocouple. To see which types
of thermocouples are supported, refer to
simulation of thermocouples is made possible by the CONN. TC,
of the diagram on page 9 or through the SN+ and SN- terminals.
The electrical connections are shown in FIG G2 (page 38). Once
the calibrator is connected and the Bluetooth connection works,

press G (signal Generator) on the APP Home screen and choose
"THERMOCOUPLE".

Then select the type of thermocouple you want to simulate; the

following is an example of the simulation of a type K thermocouple.
A screen relative to the simulation of type K thermocouples is dis­played on the APP. It is possible to enable or disable the compen-

sation in the cold junction, by default automatically set on internal
temperature. It is possible to change this setting by going to:

1 Settings
2 Cold junction setting

3 Enable the "Manual setting” control

4 Set the temperature value for the cold junction and then

conrm

CAUTION

Wait until the device reaches a stable thermal condition before
simulating a thermocouple.

If the thermocouple does not have its own connector, use the inner­most bushings SN+ SN- as an alternative, bearing in mind that the
compensation of the cold junction in this case may be less precise.

TAB 1 (page 50).

The

29MI004962-EMSC

RESISTANCE THERMOMETER SIMULATION (RTD)

The calibrator is able to simulate a resistance thermometer (RTD)
connected to the 2, 3 or 4 wire bushings. The types of supported

RTDs are listed in TAB 1 (page 50).

To carry out RTD simulation, connect the calibrator according to
FIG.G4 (page 38).
Once the calibrator is connected and the Bluetooth connection

works, press G (signal Generator) on the APP Home screen and

choose "RTD".
Then select the type of RTD that you want to simulate; the sim­ulation of a PT100-type resistance thermometer is shown as an

example.

Then enter the desired value in °C and conrm; it is possible to
switch the display of the unit of measurement from °C to Ω.

Thermal resistance generation can be divided into two scales; the
PT100 scale and the PT1000 scale (which includes the PT500).
For these two scales the excitation current from the external instru­ment must remain within a certain range (see table on page 50) . If
this condition is not met, an Generation error is signalled, indicating
the possibility that the simulated resistive value is not correct.

CAUTION

30 MI004962-E MSC

LOAD CELL SIMULATION

The calibrator can simulate a load cell (LOAD CELL) with a nomi­nal resistance of 350 Ω. The connection is made by 4 wires through
the bushings EX+ EX-, SN+ SN-. The supply voltage applicable
to the external bushings has a range from 5V to 10V. To simulate

a load cell, connect the calibrator according to FIG. G6 (page 39).
Once the calibrator is connected and the Bluetooth connection

works, press G (signal Generator) on the APP Home screen and
then select "LOAD CELL".

From the load cell screen, proceed to set the parameters by follow­ing the steps below:

1 Settings
2 Options
3 Set the parameters "Unit of measurement", "Load cell gain" in
mV/V, and then the full scale of the load cell.

For instance, once the sensitivity is set to 2 mV/V, the scale to

Kg and the full scale to 1000 Kg, simply conrm the parameters,

then return to the main page of the load cell simulation and enter

the value in Kg that you wish to simulate. The value can also be

entered as mV/V

CAUTION

Wait until the device reaches a stable thermal condition before
simulating a load cell.

31MI004962-EMSC

FREQUENCY GENERATION

The calibrator can generate a square wave voltage signal with 50%
duty cycle and settable frequency and peak voltage values. The
generated signal is taken out to the bushings (SN+ SN-).

The denable properties of the pulses are:

• Value ON: value in Volts assigned to the square wave when
the signal is at high logic level

• Value OFF: value in Volts assigned to the square wave when
the signal is at low logic level.

To generate a voltage square wave signal, connect the calibrator
according to FIG. G8 (page 39).
Once the calibrator is connected and the Bluetooth connection

works, press G (signal Generator) on the APP Home screen and
then select "FREQUENCY".

To proceed with the generation, set the band parameters of the
square wave by following the following steps:

1 Settings
2 Set Pulse Parameter

3 Enter the desired Value ON / Value OFF band values and
conrm with OK

Then set the desired frequency using the numeric keypad and
make sure that the output enable button is turned to ON.

The primary measurement unit of the signal is in Hz, switchable to
seconds to show the length of the period.

32 MI004962-E MSC

CAUTION

It is important to note that the time resolution according to which

the square wave signal is generated is 50 μs. This implies an error

that is dependent on the numeric value set.
For instance, you want to generate a signal with a frequency of 150
Hz whose corresponding period is 6.666 ms; the number of counts
necessary to obtain this frequency is obtained through:

6.666 mHz /50 µs=133.33. The system then rounds off to the
nearest whole number, 133, which it will use to generate the output
signal. The output frequency will have the value:

FOUT= 1 = 150.37 Hz

133X50 µs

The APP will automatically show the value actually generated.

33MI004962-EMSC

PULSE GENERATION

The calibrator can generate a train of voltage pulses available at
the two innermost bushings (SN+ SN-).

The denable properties of the pulses are:

• Value ON / Value OFF: values in V relative to the pulse value
and to the value of the steady state of OFF respectively.

• Time ON / Time OFF: values in ms that dene the period T of

the pulse. ( T=TimeON + TimeOFF).
Time ON is the time in which the pulse remains at the Value ON
value in ms.

To generate voltage pulses, connect the calibrator according to
FIG. G8 (page 39).
Once the calibrator is connected and the Bluetooth connection

works, press G (signal Generator) on the APP Home screen and
then select "PULSE".

To proceed with the generation, set the time and band parameters
of the pulse by following the following steps:

1. Settings

2. Set Pulse Parameter

3. Enter the desired band Value ON / Value OFF values and the

times corresponding to the Time ON / Time OFF pulse period

and conrm with OK

Then set the number of pulses and press start to start the genera­tion; the remaining pulses are displayed at the same time. During
this phase it is possible to pause and then resume the generation

by pressing PAUSE or cancel it by pressing STOP.
