CS525 ISFET pH Probe
connected in the correct way to the datalogger. Any other combinations might
cause a loss of performance and irreversible damage to both probe and/or
datalogger.
1.1 Initial Inspection and Handling Guidelines
Upon receipt of the CS525, inspect the packaging for any signs of shipping
damage, and, if found, report the damage to the carrier in accordance with
policy. The contents of the package should also be inspected and a claim filed
if any shipping related damage is discovered.
Care should be taken when opening the package not to damage or cut the cable
jacket. If there is any question about damage having been caused to the cable
jacket, a thorough inspection is prudent.
The model number and cable length is printed on the cable label. Check this
information against the shipping documentation to ensure that the expected
model number and cable length were received.
Remember that although the CS525 is designed to be a rugged and reliable
device for field use, it is also a highly precise scientific instrument and should
be handled as such. There are no user serviceable parts and any attempt to
disassemble the device will void the warranty.
