WARRANTY Environmental Devices Corporation warrants only nonexpendable products, parts and labor, for a period of one year from date of shipment to the original purchaser. The warranty covers only product parts and labor that failed due to normal operation of the instrument and not due to abuse or negligence. The product will be delivered in accordance to its published specifications and free from defects in materials or workmanship.
INTRODUCTION HAZ-DUST is a portable direct reading particulate monitor that uses infrared electromagnetic radiation to sense airborne particles. The sensing method is traditionally referred to as near forward light scattering. The principle of near forward light scattering utilizes a light source emitter and a photodetector positioned at a 90-degree angle. As particles transverse the sensing volume, they scatter IR light at a forward angle of 45-90 degrees.
FEATURES A. RANGE SWITCH Hi range - This range provides the most sensitivity. The range span is from 0-20 mg/m³. Lo range - This range setting is recommended for monitoring in areas that generate more than 10mg/m³ of dust. The range span is from 0-200 mg/m³. B. ANALOG OUTPUT Although the DL-103 Data Logger is recommended, the 0-2v output can transfer its linear analog voltage to any data logging device that can accept an analog signal. This output should be utilized if hard copy documentation is needed.
OPERATION A. Start up To start measuring particle concentrations turn power switch to “on” and allow unit to warm-up for a few minutes. Set range switch to “0-20mg/m3” position. B. Battery Status and Charging. The Haz-Dust HD-1100 is powered by NiMH batteries, which have a variable lifetime that can range from 500-1000 hours. The batteries need to be replaced when they do not hold a charge for 8 hours. To check to see if batteries need charging depress “Bat” on power switch and observe reading on display.
OPERATION, Continued D. MONITORING When monitoring hold unit in the palm of your hand, or place on the optional tripod accessory 1 , so that the display is facing in the up position. Take precaution in monitoring in areas that produce high reflective light (i.e., directly next to arc welding, flash explosions, reflected sun light etc.). When necessary position the unit so that the air intake is opposite bright light. Bright fluctuation may produce erroneous data.
MAINTENANCE Annual factory re-calibration recommended. Maintenance on the unit is minimal. Replacement of the battery pack and cleaning of the sensing chamber are the most frequent procedures that must be performed. An annual re-calibration is recommended. Cleaning the instrument sensing chamber depends on the length of time and the concentration of dust the unit has been exposed to. In general, if monitoring a concentration of 1 mg/m³ for a period of 8 hours, cleaning should be performed every 24 hours.
Replacement Battery Pack for the HD-1100 Part Number BP-111 Figure 2A: Disconnect battery from nylon connectors. NOTE: DO NOT PULL ON WIRES. Figure 1: Remove six screws Figure 2B: Reconnect battery from nylon connectors. NOTE: DO NOT PULL ON WIRES. Instructions to replace battery pack 1. Remove optical cover from sensor. 2.
