keys, select the amount of filtering desired,
from none (OFF) to five seconds. When finished, press the
FUNC
key to lock in the value and
advance to the next parameter.
NOTE: The parameter group legends of instruments manufactured prior to January 1998 refer to the
primary input as “Pressure”, and the secondary input as “Temperature” regardless of the
actual process variable being indicated. When asked in the menu to “Link” an alarm to an
input. “Pressure” is always the main input (upper display), and “Temperature” is always the
secondary input (lower display).

If using a Dynisco transducer, the model number of the transducer will designate its own electrical
output. For example, in plastic melt applications, the PT462E-5M-6/18 or TPT432A-10M-6/18 have
a strain gage (0-3.33 mV/V dc full scale) signal output. Amplified units have a number where the
strain gage units have a letter (E or A). The PT4624-5M-6/18 has a 4-20 mA signal output; the
PT4625-5M-6/18 has a 0-5 Vdc signal output, while PT4626-5M-6/18 has a 0-10 Vdc signal output.
