8. Steam Trap Diagnosis

The PT1 is equipped with a simple automatic diagnosis function for steam traps. This
section explains how to properly operate PT1 for steam trap inspections.

8.1 Mode Selection

Set the mode to “Trap&Valve”. If already set to
“Trap&Valve”, the following operation is unnecessary.

a) With the power on, simultaneously press [



]



[ENT].

b) Press [



] or [



] to highlight “Trap&Valve”.

c) Press and hold [ENT] for more than 1 second.

Set the mode to “Trap”. If already set to “Trap”, the
following operation is unnecessary.

If “Valve” is highlighted, simultaneously press [



]



[



8.2 Set Record Number

1) Set the record number to use by pressing [



] or [



a) Pressing [



] / [



] once increments/decrements the

record number by 1.

b) Holding [



] / [



] for more than 1 second increments/

decrements record numbers more quickly.

Note: The record number cannot be changed after the

measurement is taken.

2) If any data is recorded at the selected record number, its contents are shown.

Note: If data is already recorded at the selected record number, taking a

measurement will overwrite the data.

3) Record numbers from 001 to 100 are available, records do not need to be saved

sequentially, and not all record numbers need to be used (numbers in the middle
can be skipped).

8.3 Take Measurement

Before proceeding with taking a measurement, be sure to read section “7. Proper
Measurement Procedure”.

1) Measurements should be taken from the inlet side of

the trap. If the measurement point is at the outlet,
measurement accuracy cannot be assured.

2) Press the probe against the measurement point.

Measurements begin automatically once the probe
is applied to the measurement point.

3) It takes 15 seconds after placing the probe against

the measurement surface for the measurement to be complete. Be sure to hold the
probe perpendicular and steady for this entire period.
