Safety
Electrical and compressed Gas Hazards
The HP125 delivered to you has been tested for safety, calibrated and approved as
shipped from the factory. Note the following precautions:
ESD Protection
Electrostatic Discharge (ESD) can cause immediate or latent damage to
electronic circuits. Edgetech Instruments products are adequately protected
against ESD for their intended use. It is possible to damage the product, however,
by delivering electrostatic discharges when touching, removing, or inserting any
objects inside the equipment housing.
1. To make sure you are not delivering high static voltages yourself when handling the
replaceable sensor tip PCB
2. Handle ESD sensitive components on a properly grounded and protected ESD workbench.
3. When an ESD workbench is not available, ground yourself to the equipment chassis with a
wrist strap and a resistive connection cord.
4If you are unable to take either of the above precautions, touch a conductive part of the
equipment chassis with your other hand before touching ESD sensitive components.
Always hold component boards by the edges and avoid touching the component contacts.
When the Probe is first introduced into the process it will need a period of time for the materials to dry
down before the sensor reads Dew Point and RH correctly.
During installation process the probe will have been exposed to ambient conditions. The stainless steel
filter and the tip PCB will have absorbed some moisture.
Once installed in the process any entrained moisture will be drawn off by the process gas and the unit
will quickly reach equilibrium.
The initial RH and Dew Point values displayed when first installed may be misleading
