General
This section summarizes the essential precautions applicable to the GPR-1500AIS ppm Oxygen Transmitter. Additional
precautions specific to individual transmitter are contained in the following sections of this manual. To operate the transmitter
safely and obtain maximum performance follow the basic guidelines outlined in this Owner’s Manual.
Caution: This symbol is used throughout the Owner’s Manual to Caution and alert the user to recommended safety and/or
operating guidelines.
Danger: This symbol is used throughout the Owner’s Manual to identify sources of immediate Danger such as the presence of
hazardous voltages.
Read Instructions: Before operating the transmitter read the instructions.
Retain Instructions: The safety precautions and operating instructions found in the Owner’s Manual should be
retained for future reference.
Heed Warnings: Follow all warnings on the transmitter, accessories (if any) and in this Owner’s Manual.
Follow Instructions: Observe all precautions and operating instructions. Failure to do so may result in personal
injury or damage to the transmitter.
Pressure and Flow
Inlet Pressure: GPR-1535 GB PPM Oxygen Transmitter is designed for measuring the controlled atmosphere inside a glove
box. Calibration requires a flowing sample using the Glove Box Housing Assembly (refer to photo section 4 Specification) which
is equipped with 1/8” tube fitting connections and are intended to operate at positive pressure regulated to between 5-30 psig.
Outlet Pressure: The sample gas vent pressure should be atmospheric.
Installation
Oxygen Sensor: DO NOT open the sensor. The sensor contains a corrosive liquid electrolyte that could be harmful if touched
or ingested, refer to the Material Safety Data Sheet contained in the Owner’s Manual appendix. Avoid contact with any liquid or
crystal type powder in or around the sensor or sensor housing, as either could be a form of electrolyte. Leaking sensors should
be disposed of in accordance with local regulations.
Mounting: The transmitter is approved for indoor use. Mount as recommended by the manufacturer.
Power: Supply power to the transmitter only as rated by the specification or markings on the transmitter enclosure. The wiring
that connects the transmitter to the power source should be installed in accordance with recognized electrical standards and so
they are not pinched particularly near the power source and the point where they attach to the transmitter. Never yank wiring
to remove it from a terminal connection. Power consumption is 30 watts, 40 watts with the optional DC powered heater.
Operating Temperature: The maximum operating temperature is 45º C on an intermittent basis unless the user is willing to
accept a dramatic reduction in expected sensor life – refer to analyzer specification where expected sensor life is specified at
less than 1000 ppm oxygen at 25°C and 1 atmosphere of pressure.
Heat: Situate and store the transmitter away from sources of heat.
Liquid and Object Entry: The transmitter should not be immersed in any liquid. Care should be taken so that liquids are not
spilled into and objects do not fall into the inside of the transmitter.
Handling: Do not use force when using the switches and knobs. Before moving your transmitter be sure to disconnect the
wiring/power cord and any cables connected to the output terminals located on the transmitter.
