    DAMAGE IS NOT COVERED BY THE PRODUCT’S WARRANTY. Please read the following carefully before deploying the product. Contact DATAQ Instruments Support at 330-668-1444 for all questions. This product can tolerate a maximum applied voltage of only ±20V peak without damage. Although you may be cer- tain that the signal you want to measure is lower than this level, a common mode voltage (CMV) with an unknown value may combine with your signal of interest to exceed this ±20V limit.
