Digits
The display resolution of the measured reading depends on the DIGITS setting.
This setting is global, which means the digits setting selects display resolution for
all measurement functions.
The DIGITS setting has no effect on the remote reading format. The number of
displayed digits does not affect accuracy or speed. Those parameters are con-
trolled by the SPEED setting.
Setting display resolution
There are two ways to set display resolution:
DIGITSPress the DIGITS key until the desired number of digits is dis-
played.
CONFIG DIGITSPress CONFIG and then DIGITS to display the digits
menu. Place the cursor on the desired number of digits (3.5, 4.5, 5.5, or
6.5) and press ENTER.
NOTE The concurrent measurement (available on the secondary display by
using the TOGGLE key) is always 5
H
digits.
Changing SPEED changes DIGITS, but changing DIGITS does not
change SPEED.
