Pressure Calibrator with Electric Pump
Introduction
3
• Make sure the battery door is closed and
latched before operating the Calibrator.
• Do not operate the Calibrator if it is
damaged.
• Do not operate the Calibrator around
explosive gas, vapor, or dust.
• When using probes, keep fingers behind
the finger guards on the probes.
• Use only two 9 V batteries, properly
installed in the Calibrator case, to power
the Calibrator.
• Follow all equipment safety procedures.
• Turn off circuit power before connecting
the Calibrator mA and COM terminals in
the circuit. Place Calibrator in series with
the circuit.
• When servicing the Calibrator, use only
specified replacement parts.
• Do not allow water inside the case.
• To avoid false readings, which could
lead to possible electric shock or
personal injury, replace the battery as
soon as the battery indicator (B)
appears.
• To avoid a violent release of pressure in
a pressurized system, shut off the valve
and slowly bleed off the pressure before
attaching or detaching the internal
pressure sensor or pressure module
fitting to the pressure line.
• To avoid over pressure damages, do not
apply pressure that exceeds the limits
listed in the Pressure Specifications
table in the Specifications section.
• To avoid mechanically damaging the
Calibrator, do not apply torque between
the pressure fitting and the Calibrator
case. See Figure 1 for the proper use of
tools.
• To avoid misleading readings,
disconnect the pressure module
connector at the Calibrator.
• To avoid damage to the pressure
module, refer to the related Instruction
Sheet.
• To avoid damage to the pump, use with
dry air and non-corrosive gases only.
• Check test leads for continuity before
using. Inspect Calibrator for cracks or
damage, do not use the probes if they
are damaged or show high resistance.
