Includes high-intensity and BCD-output models.
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.
See Technical Notes.
BCD outputs are optional and must be specified in the part number.

in erroneous readings.

procedure. Pin 7 should be left open in most common applications.
It can be used in certain "ratiometric" applications in which it is
desirable for the meter’s reference to track an external reference.

"–18888" regardless of the actual applied input. To reduce self-
heating, the display should not be left in the "test" mode for
more than 10 seconds. This pin should be left open if unused.

active low functions. Select the appropriate decimal point by tying
pin 4, 5, 6 or 8 to pin 3 (5V RETURN). Unused decimal point
location pins should be left open.
BCD Output Models:
A panel-mount retaining clip is supplied with each model.
Accessories:
BCD outputs are only available on standard red meters.
