Page 15: Measurement Ranges
Model UT60D: OPERATING MANUAL Measurement Ranges (1) A measurement range determines the highest value the Meter can measure. Most Meter functions have more than one range. See "Accuracy Specifications." A. Selecting a Measurement Range Being in the right measurement range is important: If the range is too low for the input, the Meter displays to indicate an overload. - Page 16 Model UT60D: OPERATING MANUAL Measurement Ranges (2) To exit the manual range mode, press and hold RANGE for over one second. The Meter returns to the autorange mode and is displayed. Note If you manually change the measurement range after entering Hold mode, the Meter exits this mode.
