a. There are two possible entries for measurements made with the preamplifier on,

depending upon the ambient temperature. The first entry is for measurements

made with an ambient temperature outside of the 20° to 30° C range, but within

the 0° to 55° C range. The second entry is for measurements made with an ambi-

ent temperature within the 20° to 30° C range.
