Instruction:
PM-3000 Intelligent Pressure Gauges have full electronic structure
and use battery-powered, so they are very
easy for on-site installation. Specifically, front-end
high-precision piezoresistive pressure sensor is used and the
output
signal is processed by the high-precision, low temperature drift
amplifier, then sent into the high-precision A/D
converter to be converted into digital signal, after computing and
processing the actual pressure value is showed on
the LCD display.
Features:
The housing is water proof , widely applied for outdoor application
Accuracy can reach up to 0.25%
4 1/2 local display
Using slot for fixed , needn't srews at all , style designed by
America company
Applications:
Hydraulic/Pneumatic Control Systems
Energy and Water Management
Automation equipment
Process control
Chemical

Operating Manual
1.Summary
PM-3000 Digital Pressure Gauge Series are designed for pressure
applications that involve measurement of any media compatible with
316 stainless steel. Designed for battery operation, this digital
gauge has an automatic shutoff feature allowing the user to walk
away after taking a reading .Water-proof housing adopted for harsh
environment is our big advantage.

5. Installation
PM-3000 can be directly mounted in the hydraulic pipe through the
pressure pipe joints (M20*1.5) other size fittings available when
ordering .In critical applications , such as severe vibration or
shock , pressure hose pipe connection can be micro-mechanical
decoupling.
Note: The range less than 100Kpa must be installed vertically.
6. Battery Replacement
Remove back cover in the direction of arrow of the unit carefully
remove battery from the holders by lifting up the positive end of
the battery (opposite the spring) .Take care not to bend or distort
the battery retention springs. Do NOT discard the old battery into
fire, any other sources of extreme heat ,or in any other hazardous
manner. Always replace both batteries at the same time with high
quality alkaline laminated batteries. Observe the polarity of the
batteries when replace them. The negative (flat) end of batteries
should be inserted first and should face the spring in the battery
holder. Replace the back cover, including the rubber sealing
gasket.
