1 IMPORTANT NOTE
Unless otherwise indicated in the text, the operating instructions contained in this publication apply to both the MICROCAL 20 DPC Multi-Calibrator instruments and the
MICROCAL 20 DPC IS Multi-Calibrator instruments.
MICROCAL 20 DPC IS IMPORTANT NOTICE !
ONLY THE INTRINSICALLY SAFE VERSION OF THIS MULTI-CALIBRATOR INSTRUMENT (MICROCAL 20 DPC IS) MAY BE USED IN HAZARDOUS AREAS AND THE FOLLOWING GENERAL WARNINGS AND
CONDITIONS OF USE SUMMARIZED BELOW ARE APPLICABLE.PAGES 113 TO 116 PROVIDE SUPPLEMENTARY INFORMATION FOR THE INTRINSICALLY SAFE VARIANTS
BEFORE USING MICROCAL 20 DPC IS, INTRINSICALLY SAFE VERSIONS OF THIS MULTI-CALIBRATOR,READ THE FOLLOWING WARNINGS AND READ AND FULLY UNDERSTAND THE SPECIAL
CONDITIONS OF USE DETAILED IN THE CHAPTER 15 OF THIS MANUAL.
IF UNSURE, CHECK BEFORE USE.
1.1 Safety warning
HIGH-PRESSURE
UNCONTROLLED RELEASE OF HIGH PRESSURE IS HAZARDOUS TO PERSONEL AND MAY CAUSE DAMAGE TO EQUIPMENT.BEFORE CONNECTION OF ANY PRESSURE COMPONENT TO THE CALIBRATOR BE
SURE 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.

1.2 Warnings for IS models
1. DO NOT exceed the maximum measurement ratings given on chapter 15 of this manual.
2. DO NOT open the instrument case in a hazardous area.
3. Batteries must ONLY be fitted in a SAFE AREA.
4. If fitted with rechargeable batteries, the batteries must ONLY be charged in a safe area and only with the Eurotron charger supplied for use with the Multi-Calibrator.
5. The RS232 communication circuit may only be used outside the hazardous area.
6. When the Multi-Calibrator, Type MICROCAL 20 DPC IS, is used as a source for intrinsically safe apparatus, that apparatus may not be connected to any other intrinsically
safe circuit simultaneously. The parameters of the apparatus must comply with the output parameters of the Multi-Calibrator.
7. To prevent electrical shocks or damage to the instrument, do not connect more than 30 V between the terminals, or between the terminals and the ground (earth).
The Intrinsic Safety for zone 0 with ATEX certification, class II 1G EEx ia IIC T4 is available. (-20°C from T Ambient to + 50°C)

2 GENERAL
MicroCal 20 DPC series are two insulated channels, multifunction calibrators. They are hand-held instruments developed to meet all the needs of instrumentation engineers and
Quality managers, both in laboratory and in fieldwork. These units are accurate, rugged, compact and easy to use. They are the best solution to simulate and measure electrical
and physical parameters: Voltage, current, resistance, thermocouple, resistance thermometers, pressure, frequency and pulse.
Advanced flexibility and high performance has been achieved using 32-bit microprocessor and a fast A/D conversion technology. The calibrators memory, has stored inside all data
for normalised IEC, DIN and JIS thermoelectric sensors for both IPTS68 and ITS90 International Temperature Scale. The microprocessor performs automatic linearization and cold
junction compensation to assure high accuracy. It is possible to set the calibrator to execute menu-driven calibration procedure for your instruments in fieldwork.
7 different models are available to meet different needs about test and calibration:
Model CH1 CH2 Internal External Basic HART EC
pressure pressure Accuracy protocol module
MicroCal 20 DPC basic IN OUT NO OPT. ±0.02% rdg OPT. OPT.
MicroCal 20 DPC plus IN OUT OPT. OPT. ±0.01% rdg OPT. OPT.
MicroCal 20 DPC XP IN IN/OUT OPT. OPT. ±0.006% rdg OPT. OPT.
MicroCal P20 basic NO NO OPT. OPT. ±0.01% rdg OPT. OPT.
MicroCal P20 plus IN (V, mA) NO OPT. OPT. ±0.01% rdg OPT. OPT.
MicroCal 20T IN IN NO NO ±0.01% rdg OPT. OPT.
Both Channel 1 (IN) and Channel 2 (IN/OUT) have the following operative mode capability: millivolts, volts, milliamperes (active and passive loop), ohms, temperature with
thermocouples, temperature with resistance thermometers, frequency, and pulse.
Optional single or dual sensors Pressure inputs can be installed inside the calibrator for gauge, absolute and differential measurements.
An external pressure sensor can be installed for measurements up to 700 bar.
Optional auxiliary measurements (EC module) with integrated sensors are: Relative humidity and temperature, Barometric pressure sensor.
Report of Calibration
Each MicroCal is factory calibrated and certified against Eurotron Standards, which 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.
