Frequently Asked Questions
What is a True RMS digital multimeter?
A True RMS (Root Mean Square) digital multimeter accurately measures non-sinusoidal AC waveforms — essential when measuring circuits with variable frequency drives (VFDs), inverters, or switching power supplies. Standard average-responding multimeters give up to 40% error with distorted waveforms. CIE DM 321T and all Vartech multimeters with TRMS designation use True RMS measurement.
Which digital multimeter is best for industrial use in India?
For industrial electrical work, a True RMS multimeter rated CAT III or CAT IV is recommended. The Vartech V 890 D (1000V DC / 750V AC, 20A, True RMS) and Vartech V 981+ (30000 counts, bench-top with PC interface) are popular choices. For general field work, the Vartech V 92 S (smart multimeter, True RMS, auto-ranging) is compact and reliable.
What is the difference between a 2000-count and a 30000-count multimeter?
Count refers to the resolution of the digital display. A 2000-count multimeter (3½-digit) reads up to 1999, meaning 1V resolution on the 20V range. A 30000-count multimeter reads 29999 — 10x finer resolution, important for precise measurements like contact resistance, small voltage drops, or component testing. Higher-count meters like the Vartech V 981+ are preferred for laboratory and precision measurement work.
About Digital Multimeters
CIE digital multimeters provide accurate measurement of voltage, current, resistance, capacitance, frequency, and temperature. The DM 321T is a True-RMS multimeter for accurate measurement of non-sinusoidal waveforms, while the DM 235 is a cost-effective 3½-digit instrument for general electrical measurement. All CIE multimeters conform to relevant IEC safety standards.
