P-61 empty calibration
this provides sound velocity compensation on an empty tank. This is
required on a volume application where the atmosphere in the tank is
other than air or the atmospheric temperature is constant but other than
20°C and no temperature sensor is being used. (F=-----)
empty tank as much as permissible. Leave filled with normal vapour and at
normal operating temperature. Refer to Figure 7.

P-62 measurement offset
this displays the measurement offset; used in conjunction with a full tank
calibration, P-60, or an offset value may be entered directly. The offset is
added to the ultrasonic measurement such that its effect will be carried
through the reading (P-39, P-76 or ) mA output and relay setpoints.
