Range
The range setting is "remembered" by each measurement function. When you select a
function, the instrument will return to the last range setting for that function.
Measurement ranges and maximum readings
The selected range affects both accuracy of the measurement as well as the maximum
level that can be measured. The measurement ranges and maximum readings for all func-
tions, except FREQ, PERIOD, and TEMP, are listed in
Input values that exceed the maximum readings cause the message "OVERFLOW" to be
displayed.

*Offset compensated ohms (OCOMP) can be performed on the 100¾, 1k¾, and 10k¾ ranges.
FREQ and PERIOD — Frequency measurements from 3Hz to 500kHz and period
measurements from 2µs to 333µs can be made on the ACV ranges.
TEMP — There is no range selection for temperature measurements. Temperature
measurements are performed on a single, fixed range. Depending on which type of sensor
is being used, the maximum temperature readings range from –200°C to 630°C.
