When the Industrial Hygiene Firmware is installed the following  two separate Dosimeter measurement sets are available for the user-selected Industrial Hygiene Standard:

Measurement Settings

• Select Industrial Hygiene Standard (OSHA-1; OSHA-2; ACGIH; NIOSH or IEC)

• Exchange Rate

• Threshold

• Criterion Level

• Criterion Time

• Auto-Calculate On/Off (automatically sets Criterion Level or Time from either input)

Data Displays

The Industrial Hygiene measurements are displayed as a Basic Data Display (Overall display) in four sections:

Sound Exposure:

• Sound Exposure Level (LE) for A/C/Z and S/F/I weightings

• Sound Exposure (actual value) E for A/C/Z & S/F/I weightings

• Sound Exposure (extrapolated values x2) for (µPa²h and µPa²s)

Dosimeter 1: 

• Time Weighted Average for X hours (LWTAX) calculated from run time measurement data

• Projected Time Weighted Average (LWTA) calculated from run time measurement data

• Daily Personal Noise Exposure (Lep,d) calculated from run time measurement data

• Value of Dose for Criterion Time based on 'Single Sample' Run Time Data (DOSE)

• Projected Dose for Criterion Time based on Run Time Data (ProjDOSE)

Dosimeter 2: (Same as Dosimeter 1)

SEA:  Integrated 1 second peaks that exceed 120dB (Canada/Province of Quebec)
