17 Segment Analogue LCD Meter
This low cost, compact indicator is ideally suited for low or high volume applications. The meter features a 17
segment LCD to display 0-1V or -1V-0-1V d.c. full scale reading. Other voltages and currents canbe indicated via
the addition of 2 external scaling resistors. The meter can be used in applications where the order of magnitude
of the reading is more important than the value ofthe reading itself. Itallows the operator to scan the display and
receive a quick visual feedback. The module is mounted into the panel, using the supplied clip. A rubber seal is
included, providing splashproof protection for the unitwhen fitted to the meter during installation.

SAFETY
To comply with the Low Voltage Directive (LVD 93/68/EEC), input voltages to the module’s pins must not exceed
60Vdc. The user must ensure that the incorporation of the panelmeter into the user’s equipment conforms to the
relevant sections of BS EN 61010 (Safety Requirements for Electrical Equipment for Measuring, Control and
Laboratory Use).

JUMPER LINK FUNCTIONS
J1. Not fitted: The module has a 0 to1V d.c. full scale range (defaultsetting).
Fitted: The module has a -1Vto +1V d.c. full scale range.
The scale annunciators (-, 0, +)are visible. This overrides links J3 and J4.
J2. Not fitted: The input voltage is not inverted(default setting).
Fitted: The input voltage is invertedinside the meter.
J3. Not fitted: The scale annunciators (-,0,+) are notdisplayed.
Fitted: The scale annunciators (-,0,+) aredisplayed. This over rides linkJ4.
J4. Not fitted: The scale annunciator (0) is notdisplayed.
Fitted: The scale annunciator (0) isdisplayed.
J BL. Not fitted: LED backlightingis not required or V+ exceeds5V.
Fitted: To switchon the LED backlighting when V+=5V, fit JBL to connectBL- to 0V.
If V+ exceeds 5V, then a seriesresistormust be fitted in the backlightingcircuit. See
the application diagrams on this datasheetfor details.

SCALING
Two external resistors may be used to alter the
full scale reading of the meter - see table for
sample values. Alter natively, use the
following formulae to calculate Ra and Rb.
Select the nearest available standard resistor.
To achieve optimum accuracy, use 1% metal
film resistors. Ensure solder link La is cut
when fitting Ra.
