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.
