The T Offset value allows calibration of the temperature value displayed on the
LCD. Units (°C/°F) follow the Temp Units setting. Use <UP> or <DOWN> to add
or subtract an offset from the temperature value. The range is -5.0 to 5.0 °C or
-9.0 to 9.0 °F in 0.1° increments. Factory default is 0.0 °C.
The Temp Units setting is used to select °C or °F display of temperature. Use
<UP> or <DOWN> to select. The selection will also control available setpoint
ranges if the setpoint option is installed. Factory default is °C.
Display is used to control what information is displayed on the LCD. The
selections depend on the installed options. Use <UP> or <DOWN> to select

The Output Test value controls the analog output signal for testing purposes.
Use <UP> or <DOWN> to toggle the output signal to OFF (normal operation),
MIN (minimum output) or MAX (maximum output). The actual output signal will
depend on the PCB switch position (mA or VOLT) and the V Output setting (for
voltage operation). Press <MENU> to set it back to OFF and advance. Factory
default is OFF.
