If Passive Mode is chosen the following should be noted: In the passive mode the SPLIT2 is used without any inlets or a filter cassette on the sensing head (see page 11 for details). This mode means the instrument relies on the NIOSH 0600 method of calibration. This method uses ARD (Arizona Road Dust) as a calibration media and responds to the RESPIRABLE fraction only. -

See page 10. 4. Doing an Auto-Zero Before using the SPLIT2 to do an actual sample an AUTO-ZERO must be performed. To carry out an AUTO-ZERO in either the Passive or Pumped mode please do the following. Configure the sensing head for the type of dust fraction required, as shown in the previous page. e.g. Passive or Pumped. -

This means the SPLIT2 is now configuring all the options selected during set up ready to start monitoring Tag: 001 Very quickly a new screen will appear with all the sample details. - Page 18 Standards in the UK. Time Weighted Average result in mg/m3. This TWA is then used to correct the readings on the SPLIT2 by To correct the concentration reading on the instrument to the entering a SCALE factor into the units software. The TWA can dust cloud in your particular circumstance the following procedure is advised.

Page 22: Temperature Differences
Drastic changes in the environment temperature could affect the readings from the Split2. Temperature changes can occur, for example, when transferring between indoor and outdoor monitoring, or if the unit has been stored overnight in a cold room or vehicle, before being used in a warm room. - Page 23 COSHH OR ENVIRONMENTAL SAMPLING NOISE MONITORS TEMPERATURE, LIGHT, WORKPLACE LIGHT - NOISE - TEMPERATURE SORBENT TUBES PASSIVE BADGES PASSIVE OR ACTIVE SAMPLE MEDIA SKC Ltd 11 Sunrise Park, Higher Shaftesbury Road Blandford Forum, Dorset DT118ST f: 01258 450968 e: info@skcltd.com...
