3. Tilslut testledningerne på tværs af den komponent eller det kredsløb, der skal måles.
4. DC voltage reading will appear on the display.

5.2 Modstandsmåling (Ω)

1. Tryk på Ω funktionsknap.
2. Tilslut testledningerne til HI (rød) og LO (black) input terminals.
3. Ensure the circuit or component is de-energized before connecting the leads.
4. Connect the test leads across the resistor or circuit to be measured.
5. The resistance reading will appear on the display.

5.3 Current Measurement (DCI/ACI)

1. Tryk på DCI or ACI function button depending on the current type.
2. Connect the test leads to the dedicated 3A, 250V AMPS input terminals on the front panel.
3. Ensure the circuit is de-energized before connecting the leads.
4. Connect the multimeter in series with the circuit where current is to be measured.
5. Apply power to the circuit. The current reading will appear on the display.

For other functions like AC Voltage (ACV), Frequency (FREQ), Temperature (TEMP), and advanced settings, refer to the detailed programming manual available on the Keithley webwebsted.

6. Vedligeholdelse

6.1 Rengøring

To clean the instrument, use a soft cloth dampened with a mild detergent solution. Do not use abrasive cleaners or solvents. Ensure the instrument is powered off and disconnected from all power sources before cleaning.

6.2 Udskiftning af sikringer

If the instrument does not power on, the fuse may need replacement. The fuse holder is located on the rear panel. Always replace the fuse with one of the same type and rating as specified on the instrument (e.g., 250mA T, 100/120 VAC or 125mA T, 220/240 VAC).

1. Tag netledningen ud af instrumentet.
2. Open the fuse holder cover.
3. Remove the old fuse and insert a new fuse of the correct rating.
4. Close the fuse holder cover securely.
