SP 400-BLUE
PIN FUNCTIONS
1. V+
2. GND 0V power supply to the meter (3.0 to 7.5V meter power supply applications only).
3. BL-
4. INH Positive measuring input.
5. INL
6. DP1
7. DP2
8. DP3
9. V-
Note:
A negative supply is generated internally and mirrors the positive supply. For example: if V+ is +5V, then
the internally generated V- is -5V. When measuring with the input referenced to the same supply rail as
that of the panel meter, then the limitations on the input range are (V- + 1.5V) to (V+ - 1.5V).

CIRCUIT DIAGRAM
Positive power supply to the meter.
Connect to the meter's negative supply voltage to switch on the LED backlighting.
For meter supply voltages above 7.5V, add a series resistor Rs.
See Applications for suitable circuit diagrams.
Negative measuring input.
Connect to V+ to display DP1 (199.9).
Connect to V+ to display DP2 (19.99).
Connect to V+ to display DP3 (1.999).
Negative power supply to the meter (6.0 to 15.0V meter power supply applications only).
Normally Open. Connects INL to COM.
Normally Closed. Cut this link to disable the low battery warning sign.
