NOTE
Asmallamountofcurrentisconsumedeveninthepower-savestate.Makesure
tosettheFunctionSelectorSwitchtotheOFFpositionwhentheinstrumentisnot
used.
This function helps to avoid unwanted exhaustion of the batteries because of
leaving the instrument powered on and extend battery life. The instrument
automatically shifts to the power-save state about 10 minutes after the last
FunctionSelectorSwitchorotherswitchoperation.
Toreturnto the normalstate: Turn theFunctionSelectorSwitch or pressthe
Data Hold Button twice to exit the power-save state and enable measurement
functions.

Measurement Category:
To ensure safe operation of measuring instruments, IEC 61010 establishes safety
standardsforvariouselectricalenvironments,categorizedasOtoCATIV,andcalled
measurement categories. Higher-numbered categories correspond to electrical
environments with greater momentary energy, so a measuring instrument designed
for CATIII environments can endure greater momentary energy than onedesigned
forCATII.

7.OTHER FUNCTIONS
7-1Auto-Power-SaveFunction
NOTE
Asmallamountofcurrentisconsumedeveninthepower-savestate.Makesure
tosettheFunctionSelectorSwitchtotheOFFpositionwhentheinstrumentisnot
used.
This function helps to avoid unwanted exhaustion of the batteries because of
leaving the instrument powered on and extend battery life. The instrument
automatically shifts to the power-save state about 10 minutes after the last
FunctionSelectorSwitchorotherswitchoperation.
Toreturntothenormalstate: Turn the Function Selector Switch or press the
Data Hold Button twice to exit the power-save state and enable measurement
functions.
