Page 5: Operation Warning
6.0 OPERATION WARNING 1 ) When measuring voltage ensure that the instrument is not connected or switched to a current or resistance range. Always ensure that the correct terminals are used for the type of measurement to be made. 2 ) Use extreme care when measuring voltage above 50V, especially from sources where high energy exists. - Page 6 6.1 DC Voltage Measurements Set the Range switch to desired "DC V" range and connect the test leads across the sources or load under measurement. If the voltage range is not known beforehand, set the range switch to the highest range and work down. Read the DC voltage reading on the "DC V" scale (Black color) 6.2 AC Voltage Measurements Set the Range switch to desired "AC V"...
- Page 7 6.5 Decibel Measurements Set the Range switch to the desired "AC V" range, connect the test leads across the sources or load under measurement. For "50V AC" Range read dB reading on the dB scale directly, but for other ranges, calculate the reading with the following table:- dB Range 4 to 36 18 to 50...
