CHAPTER 3 Settings and Measurement
(6)-1 LCD brightness
Sets the brightness of the LCD backlight.
(6)-2 Screen Saver
Automatically turns off the display if the GL820 is not operated within a specified interval.
Turns off the display if not operated for some time to extend the service life of the LCD screen.
If the GL820 runs on a battery pack (B-517, option), the use of this function prolongs the drive time.
(6)-3 Power On Start
Sets the feature which initiates measurement as soon as the GL820 isturned on.
Selection item Description
Disable Disables the Power On Start function.
Enable Enables the Power On Start function.
(6)-4 Room Temp. Compensation
Selection item Description
Internal The GL820’s room temperature compensation settings are
used (usually, you use this parameter).
External This parameter is set to enable room temperature com-
pensation settings in external devices.
(6)-5 Temp. Unit
Toggles the temperature unit between °C (Centigrade) and °F (Fahrenheit) for temperature settings.
When °F (Fahrenheit) is selected, calculation is performed using the following formula:
°F (Fahrenheit) = °C (Centigrade) x 1.8 + 32
Calculate the accuracy as: Centigrade accuracy x 1.8.
(6)-6 Background Color
Sets the background colors of the waveform display area and the digital display area.
(6)-7 Burn Out
Sets a feature which checks sensor burnout in a thermocouple.
Selection item Description
Off Burnout check is disabled.
