LIMIT OF GUARANTEE / LIMIT OF RESPONSIBILITY:
SIKA guarantees the absence of faulty materials and the manufacture of this product under
normal conditions of use and maintenance. The guarantee period is one year and takes effect
on the date of delivery. Parts, repairs to the product and service are guaranteed for a period
of 90 days. This guarantee only applies to the original purchaser or the end user if he is a cli-
ent of a SIKA approved distributor and does not cover fuses, interchangeable batteries/cells
nor any product which, in the opinion of SIKA, has been badly handled, modified, neglected or
damaged by accident or subjected to abnormal conditions of use or handling. SIKA guaran-
tees that the software will function largely in accordance with its functional specifications for
a period of 90 days and that it has been correctly recorded on non-defective media. SIKA does
not guarantee that the software contains no errors or that it will operate without interruption.
SIKA approved distributors shall apply this guarantee to products sold to new clients it has not
served, but are not authorised to offer a longer or different guarantee in the name of SIKA.
Guarantee support is offered if the product was purchased by an intermediary from an SIKA
approved point of sale or if the purchaser has paid the applicable international price. SIKA
reserves the right to invoice the purchaser for the costs of importing, repair or replacement
parts if the product purchased in one country was sent to another country for repair.
The obligations under the guarantee of SIKA are limited at the discretion of SIKA, to reim-
bursement of the purchase price, or the free repair/replacement of a defective product re-
turned within the period of the guarantee to an SIKA approved service centre.
To claim for service under the guarantee, contact the nearest SIKA agent or send the prod-
uct, accompanied by a description of the problem, carriage and insurance paid (free on board
destination), to the nearest SIKA approved service centre. SIKA declines any responsibility in
the event of damage occurring during transportation. After repair under guarantee, the prod-
uct will be returned to the purchaser, carriage paid (free on board destination).
If SIKA considers that the problem was caused by abusive treatment, modification, an acci-
dent or abnormal conditions of operation or handling, SIKA will submit a quotation for the
cost of repair and will only commence the repair after receiving authorisation. After repair,
the product will be returned to the purchaser, carriage paid, and the costs of repair and
transportation will be invoiced to him.

IMPLIED, INCLUDING, BUT NOT LIMITED TO, ANY IMPLIED GUARANTEE AS TO THE
SUITABILITY OF THE PRODUCT TO BE SOLD OR APPLIED TO A PARTICULAR PURPOSE OR
USE. SIKA SHALL NOT BE HELD RESPONSIBLE FOR ANY PARTICULAR INDIRECT,
ACCIDENTAL OR CONSEQUENTIAL DAMAGE, NOR ANY CORRUPTED OR LOST DATA,

Checks the package contents:
All MC 75.2 units are mechanically and electrically checked before delivery. The necessary
precautions have been taken to ensure that they reach the user undamaged.
However, it is a good idea to make a brief check for any damage that may have occurred dur-
ing transportation. If this is the case, make an immediate claim against the carrier.
The following accessories are standard:
•This user guide
•A mounting strap
•A protection cover
•Mains unit for charging the battery pack
•Test cables
•Test terminals
If the unit is to be returned, it is preferable to use the original packaging and state as clearly
as possible, in a note attached to the unit, the reasons for its return.

1General
1.1 Introduction
The MC 75.2 is a multifunction calibrator. It is specially designed for calibration and mainte-
nance and can measure and simulate physical and electrical quantities, either on site or in
the laboratory.
It can perform all the following functions:
•Measure DC voltage and current, resistance and frequency / counts and pressure.
•Measure temperatures using thermocouples and resistive probes.
•Supply power and measure a current loop which is compatible with the HART®protocol.
•Generate DC voltages and currents.
•Simulate resistance, thermocouples and resistive probes.
•Recording of measurements and their display as a table or trend curve.
•Calibration and generation of the calibration report.
•Possibility of using calibrated sensors with memorisation of the calibration factors.
Measurement and transmission can take place simultaneously, with a double display.
In particular, it can calibrate air conditioning systems or transmitters by generating a signal
at the input to simulate a sensor and measuring the conversion current or voltage. Internal
software facilitates this operation, but it is also useful in other applications, notably in moni-
toring changes in physical quantities during processing, transformation phenomena, heat ex-
change, etc., either in development or quality testing.
The MC 75.2 has many associated functions that extend its range of application:
•Relative measurement.
•Results displayed based on a linear or other conversion law.
•Generation of increments and simple or cyclic ramps.
•Synthesis of curves.
A number of improvements have provided it with:
•Rapid access to all its functions.
•Intuitive user interface.
•Advanced on-line help system.
•Multi-functions keys defined step-by-step on the display.
•Connections which can be made with 4 mm safety plugs.
•Protection against overloads.
•Powered by a rechargeable battery with rapid internal charger.
The unit is enclosed in an ABS case with rubber sheath.

1.2.2 Housing
The MC 75.2 is delivered with a rubber sheath fitted to the case. The sheath protects the unit
from mechanical shocks and makes the side openings for the USB interface connector and
the charger connector waterproof to IP54.
1.2.3 Connection terminals
Four terminals for connection for the "measurement" function ---IN---; two of which are re-
served for 3 or 4 wire connection when measuring resistance, temperature with a resistive
probe and current for a passive transmitter (§ 2.2).
Four connection terminals for the "transmit/simulate" function ---OUT--- (§ 2.2.3).
The 8 terminals of the MC 75.2 are of the "push & lock" type. They accept 4 mm banana
plugs, bare wires, spade terminals and miniature connectors for thermocouples.

1.2.4 Side connectors
There are two connectors on the left hand side of the unit.
•The first is a mains unit connector for battery charging.
•The second is a type B USB socket for connection to a computer.
The connector for the pressure sensor is located on the right-hand side of the unit.
1.2.5 Screen
The MC 75.2 is fitted with an LCD graphical display which is backlit with white LEDs. The res-
olution of the display is 240 x 320 pixels.
