Setting the Resolution
You can select either 4½ or 5½- digit resolution for the DCV, 
DCI, resistance, ACV, ACI and frequency measurement

• 5½- digit readings have the best accuracy and noise 
rejection. 
• 4½- digit readings provide for faster readings.
• The continuity and diode test functions have a fixed, 
4½- digit display. 
• Capacitance and temperature have a fixed 3½- digit 
display. 
• For remote operation, refer to the MEASure Subsystem in
