Before you buy
Safety Rating
Always check the CAT rating. CAT III is for distribution-level circuits, CAT IV for utility-level. Higher ratings mean better protection against surges. For most professionals, CAT III 600V is sufficient, but industrial users should consider CAT IV.
Accuracy
DC accuracy is a key spec. Basic meters offer 0.5%, while precision models go down to 0.025%. For general use, 0.5% is fine; for sensitive electronics, aim for 0.1% or better.
True RMS
True RMS is essential for accurate AC measurements on non-sinusoidal waveforms like VFD outputs. If you work with modern electronics, choose a True RMS meter.
Display and Features
Consider display size, backlight, and additional features like data logging or low-pass filter. A backlit display is helpful in dim areas. Advanced features add cost but can be invaluable for specific tasks.
The wrap-up
The Triplett 9320 offers the best balance of safety, accuracy, and features for most users, while the 9360 excels in industrial settings with its CAT IV 1000V rating and high precision.
Quick answers
CAT rating indicates the meter's safety level for different electrical environments. CAT I is for low-energy circuits, CAT II for household appliances, CAT III for distribution panels, and CAT IV for utility connections. Higher CAT ratings withstand higher transient voltages.
True RMS is recommended if you measure non-sinusoidal AC signals, such as those from variable frequency drives or switching power supplies. For pure sine waves, average-responding meters are sufficient.
Yes, Triplett has a long history of manufacturing test equipment. Verified owner reviews generally praise their durability and accuracy. They comply with safety standards and offer good value for the price.
