5.7 Selecting Manual/Auto Ranging

The multimeter defaults at auto mode. To access manual ranging, operate as follows:
1. Press

button,

and measure mode option is

AUTO

2. Press

to select manual measure mode, then the ranging mode will change into

Manual

status accordingly.

3. Under manual ranging mode, keep pressing

button to reach up to the highest range,

after that, then the selected range jumps directly to the lowest range and circulates again.
The currently selected range shows just above measuring readings.

4. Press

button,

Auto

icon shows on left upper display, indicating the multimeter has returned to full

autoset mode.
