If the probe length has changed measure the length from the reference plane to the end of the
probe. Keep in mind that for a wire probe with an end weight, the probe length is
measured from the transmitter reference plane to the top of the end weight. If the wire
probe is untrimmed, it is possible to determine the correct probe length from the factory by
following these steps:
Refer to the underlined characters in the spare probe model number. For example:
SLGP2A-C-SW_ _ _ _ _ _ X X X X X-_ _-_ _. The probe length is used by the transmitter
software shown in Table 5-1. Find the matching model number pattern, calculate the probe
length accordingly, and enter into transmitter using user the interface.

Step – 5: Follow the instructions pertaining to the firmware version.
Instructions pertaining to R1.010000 firmware:
a) If a field background is being used, disable it.
b) Ensure the probe type is WIRE.
c) If the probe length was changed, ensure that the correct probe length is being used and
reset the transmitter (see above for instructions on determining the correct probe length).
d) An adjustment will have to be made to the propagation factor and vapor attenuation
depending on the wire type.
