When attentuating voltages above 20V care must be used to use components rated for higher voltages and that
proper creepage and clearance distances are used. Refer to UL3111 or IEC 1010.
** Resistors should be 1%, 1/4 wattt with a 100 or 50 ppm temperature coefficient (Note: Recalibration of span
required if accuracy better than ±1.4% is desired.)
*** Use (2) 4.99 Meg in series if 10 Meg is not available.

The input common mode range is ± 1Vdc. If INPUT (–) is not
directly conected to GND, a 10k resistor network can be connect-
ed as shown to reduce unstable readings.
Unused pins should be left open.
CAUTION: Damage to the unit can occur if the power source
polarity is reversed, or greater than 6V is applied
between pins 1 & 2.
