The following parameters can be accessed in the SETUP mode:
Slope
The current electrode slope in meter memory will be displayed. In pH
mode, the value is displayed as a percent of theoretical slope. The default
setting is 100%. This function is for display purposes only. The value can
not be changed in the SETUP menu. To change the slope value, perform a
two-point calibration or set SLOPE during a one-point pH calibration.
Press the YES key to advance to next menu function.
LogR
When the LogR function is accessed, the LogR annunciator will light up
while the upper readout displays the current LogR setting (“OFF” for
disabled and “ON” for enabled). Press the YES key to accept the setting.
To change the current setting, press a SCROLL key. Press the YES key
to accept. The measured LogR temperature will be used to calculate
temperature-compensated pH values.
Print Function
The current print function setting will be displayed in the main field
and “PrT” will be displayed in the upper field. The default is manual
print, “00”. To change the setting to “print on Ready,” press SCROLL

) key. Press the YES key when the desired setting is displayed.
When the “STD” option is selected, calibration may only be performed
with standard buffers; pH 4.01, 7.00 and 10.01. When the “SET” option is
selected, calibration may be performed with user-defined buffers within
the 0 to 14 pH range. If “SET” is selected, the meter will advance to
setting the manual buffer values. Buffer values must be at least 1 and
not more than 4 pH units apart.
