Selecting Display Resolution (3 1/2 or 4 1/2 Digits)

For most functions, you can choose whether the meter displays the reading in 3-1/2 or 4-1/2 digits.

•The 3-1/2 digit setting provides lower resolution with faster response time.

•The 4-1/2 digit setting provides greater resolution with slower response time. The 4-1/2 digit display is available with all functions except continuity, conductance, capacitance, and FAST MN MX.

To select the display resolution:

1.Press O, then T until 8888 (for 3-1/2 digits) or 88888 (for 4-1/2 digits) appears in the display.

3.Press O, then T to save the selection and proceed to the next setup selection.
