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 1200-40 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.
