3. Plug the other end of the power cord into a grounded AC power outlet (100-240V AC, 50/60Hz).

4.2 Input Terminal Connections

Connect the device under test (DUT) to the appropriate input terminals. The GPM-8213 offers both front and rear panel input terminals.

• VoltagE אַרייַנשרייַב: פאַרבינדן די וואַלtage leads from the DUT to the V+ and V- terminals. Observe polarity. Maximum input voltagE איז 600 וו אַק.
• יעצטיגע איינפלוס: Connect the current leads from the DUT to the I+ and I- terminals. Observe polarity. The front panel supports up to 10A AC, while the rear panel terminals support up to 20A AC.
• פאַרזיכערן אַז די קראַנט און וואָלtage inputs are connected correctly to avoid damage to the meter or the DUT.

4.3 קאָמוניקאַציע ינטערפייסיז

The GPM-8213 supports several communication interfaces for data retrieval and remote control:

• וסב: Connect a USB cable from the meter to a computer for virtual COM port communication.
• RS-232C: Use an RS-232C cable to connect to a computer or other serial device.
• לאן: Connect an Ethernet cable for network communication.
• GPIB (Optional): If installed, use a GPIB cable for instrument control in automated test setups.

5. אַפּערייטינג ינסטרוקטיאָנס

5.1 מאַכט אויף / אַוועק

1. Press the 'POWER' button on the front panel to turn the instrument ON.
