4. Setup
4.1 Battery Installation
The FERVE F-1830 is powered by a 9V battery (not always included). To install or replace the battery:
- Ensure the multimeter is turned OFF and test leads are disconnected.
- Locate the battery compartment cover on the back of the meter.
- Remove the screw(s) securing the cover and gently lift it off.
- Connect a new 9V battery to the battery clip, observing correct polarity.
- Place the battery into the compartment and replace the cover, securing it with the screw(s).
4.2 Connecting Test Leads
Always use the provided test leads. Connect them as follows:
- Insert the black test lead into the 'COM' (Common) input jack.
- For most measurements (Voltage, Resistance, Diode, Continuity, mA Current), insert the red test lead into the 'VΩmA' input jack.
- For high current measurements (up to 10A), insert the red test lead into the '10A' input jack.
5. Operating Instructions
This section details how to perform various measurements with your FERVE F-1830 multimeter.
Figure 5.1: The FERVE F-1830 Digital Multimeter positioned on a workbench, ready for use. The image highlights its suitability for professional applications.
5.1 DC Voltage Measurement (V=)
Measures direct current voltage from 0 to 600V.
- Connect the black lead to 'COM' and the red lead to 'VΩmA'.
- Set the rotary switch to the desired 'V=' (DC Voltage) range (e.g., 20V, 200V, 600V). If unsure, start with the highest range.
- Connect the test probes in parallel across the component or circuit to be measured.
- Read the voltage value on the display.
5.2 AC Voltage Measurement (V~)
Measures alternating current voltage from 0 to 600V.
- Connect the black lead to 'COM' and the red lead to 'VΩmA'.
- Set the rotary switch to the desired 'V~' (AC Voltage) range (e.g., 200V, 600V).
- Connect the test probes in parallel across the AC source or component.
- Read the voltage value on the display.
5.3 DC Current Measurement (A=)
Measures direct current from 0 to 10A.
- For currents up to 200mA, connect the black lead to 'COM' and the red lead to 'VΩmA'. For currents up to 10A, connect the red lead to '10A'.
- Set the rotary switch to the appropriate 'A=' (DC Current) range (e.g., 200µA, 2mA, 20mA, 200mA, 10A).
- Important: Connect the multimeter in series with the circuit. Break the circuit and insert the meter so that the current flows through it.
- Read the current value on the display.
5.4 Resistance Measurement (Ω)
Measures resistance from 0 to 2 MOhms.
- Ensure the circuit is de-energized before measuring resistance.
- Connect the black lead to 'COM' and the red lead to 'VΩmA'.
- Set the rotary switch to the desired 'Ω' (Resistance) range (e.g., 200Ω, 2kΩ, 20kΩ, 200kΩ, 2MΩ).
- Connect the test probes across the component whose resistance is to be measured.
- Read the resistance value on the display.
5.5 Continuity Test
Checks for an open or closed circuit, indicated by an audible tone.
- Ensure the circuit is de-energized.
- Connect the black lead to 'COM' and the red lead to 'VΩmA'.
- Set the rotary switch to the continuity symbol (often a speaker icon).
- Connect the test probes across the circuit or component. A continuous beep indicates continuity (a closed circuit).
5.6 Diode Test
Tests the functionality of diodes.
- Ensure the circuit is de-energized.
- Connect the black lead to 'COM' and the red lead to 'VΩmA'.
- Set the rotary switch to the diode symbol.
- Connect the red probe to the anode and the black probe to the cathode of the diode. The display will show the forward voltage drop.
- Reverse the probes. The display should show 'OL' (Open Loop) for a good diode.
5.7 Special Functions: Back Light and Hold
- Back Light: Press the 'BACK LIGHT' button to illuminate the display for better visibility in dark environments. Press again to turn off.
- Hold: Press the 'HOLD' button to freeze the current reading on the display. This is useful when taking measurements in hard-to-reach areas where the display cannot be easily viewed. Press again to release the hold function.
6. Maintenance
6.1 Cleaning
Wipe the meter with a damp cloth and mild detergent. Do not use abrasives or solvents. Ensure the meter is dry before use.
