• Make sure to install the shroud before field use to prevent damage to the sensing elements. Refer Remove or install the shroud on page 9. The probe warranty does not include such damage. • To deploy a rugged probe at a distance, toss the probe body with a slow underhand throw. Do not throw the probe by the cable to prevent damage to cable, the probe or the user. -

Figure 5 Install the shroud 7.4 Storage The storage conditions for the LDO probe can be dry, wet, or humid. Wet storage conditions help to keep the LDO sensor cap fully hydrated. Note: After 72 hours of storage in tap water, the LDO sensor cap is fully hydrated. For daily measurements in the laboratory, keep the probe in a humid environment such as a BOD bottle filled approximately ¼... -
