laboratory and in field work. This units is accurate, rugged, compact and easy to use.
2 different models are available to meet different needs about test and calibration:
Model CH1 Pressure Pressure Std. Pressure Opt. Pressure
internal external Accuracy Accuracy
MicroCal P200 basic NONE Std. AISI316 OPT. AISI316 ±0.05% FS ±0.025% FS

An external pressure sensor can be installed for measurements up to 700 bar.
Report of Calibration
Each MicroCal is factory calibrated and certified against Eurotron Standards, that are periodically certified by an Internationally recognised Laboratory to ensure traceability, and
shipped with a Report of Calibration stating the nominal and actual values and the deviation errors.
EMC Conformity
The instrument fulfils the prevision of the directive 89/336/CEE Electromagnetic Compatibility.
Quality system
Research, development, production, inspection and certification activities are defined by methods and procedures of the Eurotron Quality System inspected for compliance and
certified ISO9001 by GASTEC, a Dutch notified body.

1.1 Safety warning
HIGH-PRESSURE
UNCONTROLLED RELEASE OF HIGH PRESSURE IS AZARDOUS TO PERSONEL AND MAY CAUSE DAMAGE TO EQUIPMENT. BEFORE CONNECTION OF ANY PRESSURE COMPONENT TO THE CALIBRATOR
ENSURE THAT THE COMPONENTS ARE ISOLATED FROM THE PRESSURE SUPPLY AND ANY INTERNAL PRESSURE IS RELEASED SLOWLY.
! WARNING !
DON'T APPLY A PRESSURE HIGHER THAN 125% FULL SCALE TO THE CALIBRATOR.
IF AN EXCESSIVE PRESSURE, HIGHER THAN THE STATED ONE, IS APPLIED, PERSONNEL MAY RECEIVE INJURIES THAT COULD, IN EXTREME CIRCUMSTANCES BE LETHAL. FURTHERMORE, POSSIBLE
SERIOUS DAMAGES CAN OCCUR TO THE INSTRUMENT, THE USER’S SYSTEM AND EQUIPMENT.
RECHARGEABLE NI-MH BATTERIES
RECHARGEABLE BATTERIES MUST BE RECYCLED OR DISPOSED FOR PROPERLY. MAY EXPLODE IF DAMAGED OR DISPOSED OF IN FIRE. DO-NOT SHORT-CIRCUIT.
CAUTION: USE CHARGER SUPPLIED BY EUROTRON INSTRUMENTS ONLY.
! WARNING !
PRIMARY ELEMENTS (I.E. THERMOCOUPLES, RESISTANCE THERMOMETERS, ETC.) ARE NORMALLY LINKED TO ELECTRICAL POTENTIALS EQUAL OR NEAR TO THE GROUND POTENTIAL. HOWEVER, IN
SOME APPLICATIONS,THERE MAY BE PRESENT A COMMON MODE VOLTAGE TO EARTH.
CHECK FOR VOLTAGE BETWEEN INPUT TERMINALS AND GROUND, AS THIS VOLTAGE CAN BE TRANSMITTED TO OTHER DEVICES CONNECTED TO THE CALIBRATOR.

2.3 Power supply
MicroCal P200 can be powered from:
 internal rechargeable Ni-MH battery.
 External battery charger, supplied as a standard accessory (the batteries must be installed).
The Ni-MH rechargeable batteries allows a long time operation and do not need maintenance. The same batteries power both the instrument and the external pressure modules.
Battery life (typical):
10 h on Tc and mV input/output (backlight Off)
4 h with 20 mA simulation (backlight Off)
Recharging time (typical): 5 h at 90% and 6 h at 99% with instrument switched off.
During operation a fully battery symbol “≠” will be displayed on the display. This symbol means that the batteries are completely full. When the batteries will be discharged the
symbol “–” will appear and the instrument still has about 20 minutes operation capability to end the running analysis.
The battery symbol indicates that a full charge is required. Use only the dedicated battery charger supplied by Eurotron together the instrument.
CAUTION: OLD BATTERIES CAN LEAK AND CAUSE CORROSION. NEVER LEAVE RUN DOWN BATTERIES IN THE INSTRUMENT
WARNING
THE INSTRUMENT IS SHIPPED WITH AN AVERAGE LEVEL OF BATTERY CHARGE. AFTER UNPACKING, A FULL CHARGE OF THE BATTERY IS RECOMMENDED, BY CONNECTING THE INSTRUMENT TO THE
MAIN LINE THROUGH THE BATTERY CHARGER (OFF CONDITION) FOR 8/10 HOURS.
2.4 Electrical connections
MicroCal P200 calibrator is designed to be insensitive to transients or noise, the following recommendations should be followed to reduce ac pick up in the signal leads and to
ensure a good performance. The input leads should not be run near ac line wiring, transformers and heating elements. Input/output leads should, if possible, be twisted and
shielded with the shield grounded at the end of the cable. When shielded cables are used the shield must be connected to the negative terminal.
The following figure shows some examples of input/output wiring of the instrument:

Instruction Manual MM850470 ed.1a
15
For a better understanding of the appropriate connection when using the instrument to simulate current into industrial 2 wire loop please, note the meaning of the terminal used.
Passive loop
This type of connection is to be used when the external loop is not equipped with the loop power supplied. The calibrator can be, as an example, connected directly to a recorder,
controller, etc. with input circuits configured for current measurements.
Active loop
This type of connection must be used when the external loop is equipped with its loop power supplied. The power supply is not required to be disconnected. The loop circuit must
be opened and the calibrator connections are placed in series on the loop.

3 GETTING STARTED
3.1 Unpacking
Remove the instrument from its packing case and remove any shipping ties, clamps, or packing materials.
Carefully follow any instructions given on any attached tags.
Inspect the instrument for scratches, dents, damage to case corner etc. which may have occurred during shipment.
If any mechanical damage is noted, report the damage to the shipping carrier and then notify Eurotron directly or its nearest agent, and retain the damaged packaging for
inspection.
A label indicates the model and the serial number of the instrument. Refer to this number for any inquiry for service, spare parts supply or application and technical support
requirements. Eurotron will keep a data base with all information regarding your instrument.
3.2 Charging the battery
Before you use the calibrator for the first time, charge the battery pack for 8/10 hours by connecting the external battery charger.
3.3 Power up
Press the [ON/OFF] key to switch the instrument on and off. The instrument needs some seconds to check the hardware and to run the autocalibration procedure.
3.4 Automatic channel protections
The Microcal P200 unit, is protected against over-voltage and over-current inputs, by firmware and by thermal fuses.
The firmware is designed to automatically set the channel 1 to the maximum impedance input (20 V f.s. range) and to set the channel 2 in off condition.
The thermal fuses do not need replacement when activated. They automatically restore the input channels after some minutes.
IMPORTANT
WHEN THERMAL FUSES ACTIVATE, YOU SHOULD DISCONNECT THE ELECTRICAL CONNECTIONS FROM THE UNIT AND SWITCH THE INSTRUMENT OFF FOR ABOUT 2 MINUTES. THE THERMAL FUSES WILL
BE AUTOMATICALLY RESTORED AND YOU CAN RESUME YOUR WORK.
3.5 Date and time setting
Before you use the calibrator for the first time, adjust the current data and time of the unit.
• Switch the instrument ON by pressing the [ON/OFF] key.
