7.6 Extended Settings
The last few settings are grouped together to prevent them from being adjusted by
accident. To gain access to the extended settings, select On using the S or T buttons and
press the  button.
7.7 Speed of Response
The speed of response for both displayed and output values of mg/L can be adjusted in
this menu. Although the default setting is 10, sixty-one (0-60) response speeds are
available. The displayed number is a response time, in minutes. Cycle Times do not affect
the response time. Select the desired speed of response using the S and T buttons. Press
the  button to accept it.
To avoid reading air and other anomalies, select the slowest speed (60). Select the fastest
response (0) where monitoring of rapid changes is needed.
7.8 LCD Backlight Brightness
The LCD backlight brightness may need to be adjusted. This is of particular interest if
multiple instruments are located in the same area and it is desired for the entire group to
have the same appearance. Ten levels are available. The default brightness is 8.
Change the brightness by pressing the S or T button. When the desired brightness has
been selected, press the  button.
