How to Use
Begin by selecting the appropriate measurement function using the rotary selector dial, positioning it toward the measurement type you require: DC voltage, AC voltage, DC current, AC current, or resistance. Insert the black test lead into the common terminal and the red test lead into either the voltage/resistance terminal or the current terminal depending on your measurement. For voltage measurements, connect the probes in parallel across the component or circuit node without interrupting current flow. For current measurements, break the circuit path and insert the multimeter in series, ensuring the red probe connects toward the positive supply.
When measuring AC voltage on unknown circuits, always start with the highest range setting and work downward to prevent display overflow and potential meter damage. For resistance measurements, ensure the circuit is completely de-energized before connecting probes to prevent false readings and internal component damage. The automatic range selection feature will adjust the display scale automatically, but you can manually select specific ranges by rotating the dial to fixed range positions for precise measurement control. Always verify the selected range matches your expected measurement value before taking readings, and disconnect the test leads immediately after completing measurements to preserve battery life.
Frequently Asked Questions
What is the difference between True RMS and average RMS measurement in the HT118A?
True RMS technology measures the actual root mean square value of AC waveforms regardless of their shape, providing accurate readings on distorted or non-sinusoidal signals like those from variable frequency drives and switching power supplies. Average RMS meters assume sinusoidal waveforms and calculate readings based on peak voltage, producing significant errors when measuring non-linear loads. The HT118A uses True RMS, making it suitable for modern electronic equipment diagnostics where harmonic distortion is common.
Can the HT118A measure both AC and DC current simultaneously?
No, the HT118A measures either AC or DC current, not both simultaneously. You must select the appropriate current measurement mode using the rotary dial before connecting the test leads. This design ensures measurement accuracy and prevents internal circuit confusion. Always verify the correct mode is selected before inserting the meter into a circuit path to avoid incorrect readings.
What precautions should I take when measuring high voltages above 300V?
When measuring voltages above 300V, always use the 600V range setting to ensure adequate safety margin. Keep one hand in your pocket or behind your back to prevent accidental two-hand contact with live circuits. Never touch the metal probe tips while they are connected to energized circuits. Ensure the test leads are in good condition with no exposed wire or damaged insulation. Consider using insulated probe covers for additional safety when working in high-voltage industrial environments.
