Before use, familiarize yourself with the meter's layout. Gently turn the two zero-adjustment knobs to ensure accurate readings. Select the correct sockets and insert the red and black test leads into their proper jacks. Set the rotary switch to the appropriate range. When reading the scale, view it perpendicularly to avoid parallax. After every measurement, return the switch to the highest AC-voltage range. Periodically check the internal battery for leakage or deterioration. Operate the meter in a clean, dry environment free from vibration and strong magnetic fields.

• Verify that the battery is fresh and that the circuit under test is de-energized.
• Choose a multiplier setting that places the pointer near the middle of the scale.
• After every range change, short the probes and re-zero with the Ω-adjust knob.
• Ensure firm contact between the probe tips and the test points, and avoid touching both probes or the component leads with your fingers.
• For simple continuity checks, use the ×1 kΩ range or higher.
• Remember that different ranges may give different results when testing diodes or transformer windings because the test current and voltage vary.

• Know the meter's internal resistance (impedance) to understand its loading effect.
• Always have a second person present when measuring high or unknown voltages.
• Connect the meter in parallel with the circuit; never change ranges while the circuit is live.
• For DC measurements, correctly identify positive and negative terminals.
• In inductive (high L) circuits, do not break the power while the meter is connected.
• For kilovolt measurements, use only the manufacturer's special high-voltage probes and leads.

1. Set the switch to the highest mA range that still exceeds the expected current.
2. Identify the polarity of the circuit.
3. Break the circuit and insert the meter in series.
4. If the reading is much smaller than the range, step down to a more sensitive range for better accuracy.

• Set the meter to a low-mA DC range.
• Connect one phase winding to a low-voltage DC source (e.g., a 1.5 V cell) in series with the meter.
• Observe the pointer's deflection direction at the instant power is applied; the terminal where current enters is the "start" and the other is the "end."
• Reverse the connections and repeat to confirm; the deflection should reverse.

• After the motor has been run recently, residual magnetism remains.
• Connect the meter to any two leads and manually rotate the shaft.
• If the pointer swings in the same direction each half-turn, those two leads are the start and end of the same phase.
• Repeat for the remaining phases to establish all start/end relationships.
