Note: 1 The voltage is specified as a range. However we do need a specific voltage to be specified to use at test and inspection. Consequently when enquiring a
specific voltage within the range must be specified. Device will function over the entire range, however the full specification is guaranteed within ±5 of specific
voltage.
