1. Additional error beyond
±1°C, but within ±5°C of last
A CAL.
2. Specifications apply full
scale to 1/20 full scale,
sinewave input, crest factor
= 1.4, and PRESET. Within
24 hours and ±1°C of Iast
ACAL, Lo to Guard switch

Maximum DC is limited to
400 V in ACV function.
Add 2 ppm of reading
additional error for factory
traceability of 10V DC to US
NIST.
