Continuity Test; Pressure Measurement - Fluke 753 User Manual

Continuity Test

When you do a continuity test, the beeper sounds and
Short is shown on the display when the resistance between
the MEASURE jack and its common jack is less than
25 . Open is shown when the resistance is larger than
400 .
To do a continuity test:
1. De-energize the circuit under test.
2. If necessary, push  for MEASURE mode.
3. Push q twice so that Open is shown.
4. Connect the Product to the circuit under test. See
Figure 12.

Pressure Measurement

Many ranges and types of pressure modules are available
from Fluke. See "Accessories". Before you use a pressure
module, read its instruction sheet. The modules are different
in how they are used, zeroed, what types of process
pressure media are allowed, and accuracy specifications.
Figure 13 shows gage and differential modules. Differential
modules also operate in gage mode when you leave the low
fitting open to atmosphere.
To measure pressure, attach the applicable pressure
module for the process pressure you will test as described
in the module's Instruction Sheet.
To measure pressure:
 Warning
To prevent personal injury, shut off the valve
and slowly bleed off the pressure before
attaching the pressure module to the pressure
line to avoid a violent release of pressure in a
pressurized system.
