10. Test and Calibration

As a unique feature, all sampled gas sensor modules are fully tested during Renesas’ final test. The final test parameters in Table 10 are applied

for each ZMOD4410. All sensor modules are pre-stabilized in the final test although the user might see a small change in the module’s raw

signal during an initial warm-up phase during the first operation. The gas sensor module qualification is based on JEDEC (JESD47) and its

subsequent standard (JESD22, JESD78, etc.); it has been tested for a lifetime of 10 years. Renesas has proven a MOx lifetime of over 15+

years in actual continuous operation in conditions without exposures to stressful environments.
