9.0 Warranty 9.0 Warranty
ENMET warrants new instruments to be free from defects in workmanship and material under normal use for a period
of one year from date of shipment from ENMET. The warranty covers both parts and labor. Equipment believed to be
defective should be returned to ENMET within the warranty period (transportation prepaid) for inspection. If the
evaluation by ENMET confirms that the product is defective, it will be repaired or replaced at no charge, within the
stated limitations, and returned prepaid to any location in the United States. ENMET shall not be liable for any loss or
damage caused by the improper use of the product. The purchaser indemnifies and saves harmless the company with
respect to any loss or damages that may arise through the use by the purchaser or others of this equipment.
This warranty is expressly given in lieu of all other warranties, either expressed or implied, including that of
merchantability, and all other obligations or liabilities of ENMET which may arise in connection with this equipment.
ENMET neither assumes nor authorizes any representative or other person to assume for it any obligation or liability
other than that which is set forth herein.
9.1Repair of Certain Units
The warranty does not apply to equipment returned in either of the conditions defined below. These are not the result
of defective workmanship or material. We will renovate and return at owner's expense.
a) Gross Recalibration: We calibrate all ISA-RAL-M's according to the customer order before shipping. Changing the
potentiometers voids the warranty, except when following the calibration procedures (Sec. 6.0). When we receive
such a unit for repair, and no defects exist, we will diagnose the problem and recalibrate the unit according to the
original order.
b)Gross Sensor Contamination: The MOS sensor is durable. It can be purged of normal contaminants by operating
the unit in the PURGE mode for a sufficient length of time. Gross contamination usually occurs during misuse.
Here are three examples of gross sensor contamination:
Close exposure to an open gas flame.
Dipping the sensor in lacquer.
Continuous exposure to heavy concentrations of industrial vapors.
A grossly contaminated sensor must be replaced. If we receive such a unit, we will diagnose the problem, replace the
sensor and recalibrate the unit.
