Introduction
digit meters operating in the single-ended mode (SG5 closed) using the
meter's internal reference (SG13 closed). This configuration is the most
common and works well for most simple voltage measurements.
and DMS-40 meters. However, Application 5, installing the span (R4) and
offset (R5) adjust potentiometers, can only be used with DMS-30 meters.
Also note that some of the other applications require the installation of
R4 and R5. See Technical Note 5 when using the DMS-EB with DMS-40
meters.

(aligning pin 1 to pin 1). After soldering, carefully connect +5Vdc to +V
(J1, pin 5) and power return to –V (J1, pin 6).

40LCD-X/X-9 meters cannot be used in single-ended input configura-
tions, i.e., LO (J1, pin 2) cannot be connected to GND (J1, pin 6). When
operating from a 7.5 to 14Vdc power source with a single-ended
input, use a +5V-powered meter and install U1 (see Battery Operation
section and Technical Note 4).

R1 and R2 in DMS-30 applications, and 0.5%, or better, in DMS-40
applications. Using tight-tolerance resistors in input divider networks
allows most final calibration adjustments to be made with the meter's
rear calibration pots through the access holes provided. Make sure
the resistor power and voltage ratings are adequate for the given
application.
Battery Operation section is rated for a 150mA LED meter or a 35mA
backlit LCD meter. A 10μF/35V tantalum capacitor (C2) should be
installed with the polarized end next to the + symbol on the DMS-EB.
This is especially important if the power supply is located far from U1.
40LCD meters, be sure to open SG13. The RN-DMS resistor acces-
sory kit comprised of resistor R3 and potentiometers R4 (Gain/Span)
and R5 (Offset/Zero), cannot be used with DMS-40 series meters. To
change the input range on DMS-40LCD meters from the low range to
the high range, close SG16.
holes on the DMS-EB provide access to the ¾-turn calibration poten-
tiometer on DMS-30 meters and the 3-turn potentiometer on DMS-40
meters. The adjustment range of both pots is very narrow. See the
applicable product data sheet for more information on each meter’s
calibration potentiometers.
connects J1, pin 2 (LO) to power return J1, pin 6 (GND) and configures
the meter for single-ended operation, that is, the low side of the input
is at system ground or zero Volts. SG5 must also be closed when
measuring floating inputs. Floating inputs are signals which have no
electrical connection, or reference to, the power supply which powers
the meter.
In applications in which input LO is connected to ground elsewhere in
the system, and SG5 is closed, unwanted ground-loop induced display
errors may develop. Ground loops, a condition in which display drive
currents also flow through the input signal wiring, can cause unstable
display readings. If this occurs, try opening SG5 to see if the display
stabilizes.
SG5 must be open when measuring differential inputs that are refer-
enced to the same supply which powers the meter. DMS Application
