This manual is intended to provide basic information regarding this meter and to describe common test procedures which can be made with this unit. Many types of appliance, machinery, and other electrical circuit measurements are not addressed in this manual and should be handled by experienced service technicians.
- Page 3 3.0 OPERATING INSTRUCTIONS DIAL SETTINGS AC Volts Resistance DC Volts 3.1 AC VOLTS There are two ranges for measuring AC voltage: 200 V and 500 V. For more accurate measurements under 200 volts, use the 200 Volt setting. 1. Connect the black test lead to the “COM” terminal and the red test lead to the “V/Ω” input terminal. 2.

Questions and answers
Is their a way to adjust the DC voltage? My multimeter "s measurement is high compared to known voltage.
To adjust DC voltage measurement on the GB GDT-311:
1. Connect the black test lead to the "COM" terminal and the red test lead to the "V/Ω" input terminal.
2. Set the function/range switch to the appropriate DC voltage range: 2000 mV, 20 V, 200 V, or 600 V.
3. Use the lowest range possible without exceeding the expected voltage for more accurate measurements.
4. Read the value displayed. A "-" sign indicates reversed lead polarity.

Hello, Is the expected reading to display when first turning on the GDT 311 multimeter prior to checking resistance?
When first turning on the GB GDT-311 multimeter before checking resistance, the expected reading should be "OL" (over-limit) or a similar indication, meaning no continuity or infinite resistance.
