GENERAL SAFETY INFORMATION
Intended Use
The 3M™ WIBGET™ Heat Stress Monitor RSS-214 is designed to measure environmental factors that can contribute to heat stress.
List of Warnings and Cautions within these User Instructions
CAUTION
Do not twist sensors once inserted into the base unit. Doing so may damage the sensor or sensor connector.
The wet bulb wick must remain wet during operation to help maintain the accuracy of the sensor.
Keep all connectors clean and dry. If a connector becomes wet, it must be thoroughly dried prior to instrument usage. Condition of the sensor receptacles may be tested by
removing all sensors, turning the unit on and checking that all functions read 0.0 ± 0.3 °C or 32.0 ± 0.5 °F. If these are not the readings, do not use until the reason has
been determined and corrected.
Do not expose dry bulb (DB) to temperatures above 65 °C (150 °F). This may damage the base unit. To monitor environments above 65 °C (150 °F), use a remote sensor
set accessory and relocate the base unit to a cooler area.
Avoid the use of harsh cleaning materials, abrasives and other organic solvents. Such materials may permanently scratch the surfaces and damage the display window,
labels, or monitor housing.
Observe proper polarity when inserting the battery. Polarity is marked on the inside of the battery compartment.
This instrument may contain a nickel metal hydride (NiMH) battery. Dispose of battery in accordance with local regulations.
WARNING
This monitor helps to measure certain environmental factors that can contribute to heat stress. Misuse may result in sickness or death. For proper use, see
supervisor or User Instructions, or call 3M in U.S.A., 1-800-243-4630. In Canada, call Technical Service at 1-800-267-4414.
Each person using this equipment must read and understand the information in these User Instructions. Use of this equipment by untrained or unqualified persons, or use
that is not in accordance with these User Instructions, may adversely affect product performance and result in sickness or death.
Use only for monitoring environmental factors which the sensors and instrument are designed to monitor. Failure to do so may adversely affect product performance and result
in sickness or death. For proper use, see supervisor or User Instructions, or call 3M in U.S.A., 1-800-243-4630. In Canada, call Technical Service at 1-800-267-4414.
Each time the unit is turned on, it performs a self-test. If the self-test fails, or an error code is displayed, do not use. Doing so may adversely affect product performance
and result in sickness or death.
The RSS-214DL RS 232 serial data output port must be used in a non-hazardous area only. Using the data output port is not an intrinsically safe operation. Failure to
do so may result in sickness or death.
Never alter or modify this instrument. Substitution of components may impair intrinsic safety. Doing so may adversely affect product performance and result in sickness or death.
Repair or replace parts only with the 3M components approved for this unit. Failure to do so may adversely affect product performance and result in sickness or death.
Battery must be replaced in a non-hazardous area only. Battery replacement is not an intrinsically safe operation. Use only approved battery. Failure to do so may
result in sickness or death.
Only charge the instrument in non-hazardous areas using a 3M battery charger (AC adapter). Battery charging and operating with AC adapter is not an intrinsically safe
operation. Do not attempt to charge alkaline batteries. Doing so may adversely affect product performance and result in sickness or death.
