➀ Each model in the DMS-40LCD Series offers two input voltage ranges that are
user-selectable via pin strapping. 5V-powered models can be used to perform either
differential or single-ended measurements. 9V-powered models can only be used for
differential measurements.
➁ Applies for transient or continuous overvoltages applied to (+) INPUT HI (pin 11)
with (–) INPUT LO (pin 12) properly connected. Pin 12 is not overvoltage protected
(see Figure 1). Voltages applied to pin 12 should not exceed the supply voltage.
➂ Listed spec applies to 5V-powered models only. For 9V-powered models, both
(–) INPUT LO (pin 12) and (+) INPUT HIGH (pin 11) must always be at least 1.5V
above –BATTERY (pin 3) and at least 1.5V below +BATTERY (pin 1).
➃ See Technical Notes.

Series offers two, user-selectable, input voltage ranges as indicated
in the Performance/Functional Specifi cations Table and the Ordering
Information. To select the higher range of any device (such as the ±2V
range for the DMS-40LCD-0/1), connect pin 2 (RANGE SELECT) to
pin 1 (+5V SUPPLY/+BATTERY). To select the lower range, leave pin 2
open.
selectable, and the decimal point control pins (DP1-DP4) are active low
functions. Select the appropriate decimal point by tying the appropriate
pin (pin 4, 5, 6 or 8) to pin 3 (5V RETURN/–BATTERY). Unused deci-
mal point location pins should be left open. For 5V-powered models,
the decimal location pins are TTL compatible and may be hard wired as
described above or driven with 5V TTL logic gates.
