To Set the Range

DM3068 provides auto and manual range selecting modes. In auto mode, the

multimeter selects a proper range automatically according to the input signal; in

manual mode, you can use the front panel key or menu key to set the range. The

auto mode can bring a lot of convenience for users while the manual mode

provides higher reading precision.

Method 1: use the front panel key to set the range

 Auto mode: Press to enable the auto range.

 Manual mode: Press

or to increase or reduce the range.

Method 2: use the menu key to select the range

 Auto range: Press Auto to directly enable the auto range.

 Manual range: Press Rng+ or Rng- to specify a desired range manually.

Note:

 “OVER LOAD” will be displayed when the input signal exceeds the current

range.

 By default, the range is set to Auto at power-on or after a reset.

 Auto mode is recommended if you are not sure about the measurement range

in order to protect the instrument and obtain accurate data.

 In FREQ/PERIOD measurements, the multimeter uses different gate times to

include all input signals within 3 Hz and 1 MHz.

 The range of CONT measurement is fixed at 2 kΩ; the range of DIODE

measurement is related to the current source currently selected.
