1. irudia: Mastech MS7221 aurrealdeko panela. This image displays the front of the Mastech MS7221 Volt/mA Calibrator. Key features visible include the large digital display at the top, showing "OUTPUT 0.000 V". Below the display are the power button (circular, labeled with a circle and vertical line), and two function selection buttons: "V/mV" (yellow) and "mA/%" (yellow). Further down, there's an "INPUT/OUTPUT" button and four arrow buttons for navigation and value adjustment. At the bottom, various input and output terminals are visible: "+LOOP", "mA INPUT", "COM", and "V INPUT/OUTPUT". Each terminal is clearly labeled with its function and maximum voltage/uneko balorazioak.
