Operating Instructions
Basic Operation
The DM-200A features auto-ranging for convenient operation, automatically selecting the correct measurement range for the input signal. This simplifies usage and reduces the chance of incorrect readings.
- Non-Contact Voltage Detection: Use this feature to detect AC voltage without direct contact, enhancing safety during electrical work.
- Data Hold and Capture: Freeze the current measurement on the display for easy reading or capture peak values for later analysis.
- Auto Power Off: The device will automatically power off after a period of inactivity to conserve battery life.
- Low Battery Indicator: An indicator will alert you when batteries need replacement, ensuring continuous reliable performance.
Advanced Measurement Capabilities
- Frequency Measurement: Measure the frequency of AC signals in Hertz (Hz).
- Temperature Measurement: Utilize the included bead temperature probe for accurate temperature readings.
- Capacitance Measurement: Measure the capacitance of various electrical components.
- AC Duty Cycle: Determine the duty cycle of AC waveforms, useful for analyzing pulsed signals.
PC Connectivity
The DM-200A is RS-232 capable and can be connected to a PC for extended measurement capability with the optional optically isolated interface DMSC-2. This allows for data logging, real-time monitoring, and advanced analysis of measurements.
Relative Offset Display Mode
Use the relative offset display mode to observe relative changes in measurements. This feature is particularly useful for comparing values against a set reference point, allowing for quick identification of deviations.

Maintenance
Cleaning
Clean the multimeter regularly with a dry, soft cloth. Do not use abrasive cleaners, solvents, or any harsh chemicals, as these can damage the casing or internal components. Ensure the device is powered off before cleaning.
Battery Replacement
When the low battery indicator appears on the display, replace the two AAA batteries promptly. Using depleted batteries can lead to inaccurate readings. Follow the battery installation steps outlined in the Setup section.
Troubleshooting
If the multimeter is not functioning as expected, consider the following basic troubleshooting steps:
- No Display/Power: Check if the batteries are correctly installed and have sufficient charge. Replace if necessary.
- Inaccurate Readings: Ensure test leads are properly connected to the correct input jacks for the desired measurement. Verify the function dial is set to the appropriate measurement type.
- No Response: If the device is unresponsive, try removing and reinserting the batteries to reset it.
