* At voltages below4.0Vd.c.,the LCD will display LO and will ultimately go blank.
At Voltagesin excess of 25.0V d.c., theLCD will display HI.
Do NOT exceed 50V d.c., asthis may damage the meter.
The module includes reversepolarityprotectionup to 30V for up to30seconds.
Operation and accuracy atvoltagesabove25.0V or below 4.0V are notspecified.
SAFETY
To comply withtheLow VoltageDirective(LVD 93/68/EEC), input voltagestothe module’s wires must notexceed60Vd.c. The user must ensurethatthe incorporation
of the meter 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).

AUTOMOTIVE AND MARINE PROTECTION
Fig. 1
Automotive and maritime applications can create harsh conditions for electronic devices. Fig. 1 shows the type of protection we recommend is added
when the EMV 1200 is used in an application of this nature. We suggest a high wattage 33 ohm resistor is used in series with two 5W zener diodes
where the value of each zener is at least 3V higher than the maximum you intend to measure. Alternatively it is possible to use a single 1500W
transient voltage suppressor (TVS) in place of the zener diodes. In addition it is recommended that the meter is connected as close to the battery as is
convenient.
