4. Luk batterirummets dæksel forsvarligt.

5.2 Tilslutning af testledninger

Use the provided test cables with alligator clips for connecting the calibrator to the circuit or device under test.

1. Identify the input/output terminals on the PCE-123.
2. Connect the red test lead to the positive (+) terminal and the black test lead to the negative (-) or common terminal.
3. Ensure connections are firm and secure before powering on the device or applying signals.

6. Betjeningsvejledning

The PCE-123 allows for both signal simulation (output) and measurement (input) of various electrical parameters.

6.1 Tænd/sluk

Tryk på ON/OFF button to power the calibrator on or off.

6.2 Selecting Measurement/Simulation Mode

Use the mode selection switch or buttons (refer to device markings) to choose between different signal types (mA, mV, V, Hz, °C/°F) and between simulation (output) or measurement (input) functions.

6.3 mA DC Current (Simulation/Measurement)

• Områder: 4 to 20mA, 0 to 20mA, 0 to 24mA.
• Opløsning: 1µA.
• Operation: Select the desired mA range. Use the numeric keypad to input the target current value. The calibrator can simulate current with a maximum load of 1kΩ when powered by 24V.
• Alarm: An audible beep will sound if there is a short circuit or if the output current exceeds 1mA during certain operations.

6.4 mV / V DC (Simulation/Measurement)

• Områder: 0 to 100.00 mV, 0 to 1.0000 V, 0 to 10.000 V.
• Opløsning: 10 µV (mV), 1 mV (V), 1.0000 V (V).
• Operation: Select the mV or V mode. Input the desired voltage value using the keypad. The calibrator provides power at 1mA for these measurements.
