If the test is to be repeated press ZERO to immediately begin
another test.
To exit Leak Decay Teat mode press either ESC or MENU to
return to measurement mode.
The HHC can be used with most standard RTD (Resistive
Temperature Detector) probes to provide precision tempera-
ture measurements. An XXX –RT1 or XXX –RT2 Quick-Select
module is needed to interface an RTD probe to the HHC. There
are two XXX -RT Quick-Select module types available to sup-
port RTD resistance levels and capabilities indicated in the
table below:
Both modules can display temperature units of Fahrenheit,
Celsius, Kelvin, Rankine, and also support reading output in
units of ohms.
The electrical interface of the probe to the module incorporates
a Switchcraft TA4M type connector and requires an RTD with
the appropriate mating connector. The connector is available
through the supplier of your choice.
Setting up the PTE-2 for an RTD Temperature Measurement
Insert the appropriate XXX-RT Quick-Select RTD Interface
Module.
Connect the desired RTD probe to the Switchcraft connector
on the XXX-RT module.
Note: RTD probes can be connected using two, three or four
wire configurations. Use of four wire configuration is recom-
mended for optimum accuracy. RTD probes provided by this
manufacturer are of the four wire configuration.
