Manual d'instruccions del calibrador RTD MASTECH MS7222

1. Introducció

The MASTECH MS7222 RTD Calibrator is a specialized tool designed for the calibration of Resistance Temperature Detector (RTD) transmitters, including those with pulsed outputs. This instrument is capable of both simulating and measuring seven distinct types of RTDs, with readings displayed in either Celsius (°C) or Fahrenheit (°F), as well as resistance in ohms. It is important to note that the MS7222 cannot simultaneously function as a source and a measurement tool.

6.4 Input (Measurement) Mode

1. Premeu el botó ENTRADA/SORTIDA button until "INPUT" is indicated on the display.
2. Connect the RTD to be measured to the appropriate input jacks using the test leads.
3. The calibrator will display the measured temperature or resistance value.

6.5 Output (Simulation) Mode

1. Premeu el botó ENTRADA/SORTIDA button until "OUTPUT" is indicated on the display.
2. Select the desired RTD type using the TIPUS RTD botó.
3. Connect the device under test to the appropriate output jacks using the test leads.
4. Utilitza el Fletxa amunt / avall buttons to adjust the desired temperature or resistance value.
5. For quick adjustments, use the +25%, 100%, -25%, 0% buttons to set common percentage values of the full scale.

6.6 Simulating Additional RTDs (Ohms Output)

The calibrator can simulate additional RTD types by using its Ohms output function. Refer to the RTD resistance tables for the specific RTD type you wish to simulate and manually set the corresponding resistance value in Ohms output mode.

7. Manteniment

7.1 Neteja

Wipe the calibrator with a soft, damp cloth. Do not use abrasive cleaners or solvents. Ensure the device is powered off and disconnected before cleaning.

7.2 Substitució de la bateria

When the low battery indicator appears on the display, replace the batteries as described in Section 5.1. Always use fresh batteries of the specified type.

7.3 Canvi de fusibles

If the calibrator fails to power on or function correctly, a fuse may need replacement. Refer to the safety warnings on the back panel for the correct fuse specifications (F: 0.125A/250V 5x20 DC60V NEDA1804 GF22.006P). Always disconnect power and test leads before attempting fuse replacement. If unsure, consult qualified service personnel.
