2.4.4. Check temperature compensation probe (optional)

If you are using the optional temperature compensation probe, make sure

that the probe is securely installed. Make sure the connectors and the

wiring from the probe to the AT30 are in satisfactory condition.

If there is a failure of the temperature compensation probe, or the wiring,

the AT30 charger displays the error code E 08.

2.4.5. Measuring the output ripple voltage (filtered models only)

If your AT30 is a filtered model, measure the ac ripple at the battery

terminals at least once a year. Use an rms responding ac voltmeter.

the battery ampere-hour capacity is at least four (4) times the output

current rating of the AT30, the ripple voltage should be no higher than the

value featured in the specifications in Appendix A on page 64.

If you suspect that the output ripple voltage is too high, see "Output ripple

voltage too high" of the Troubleshooting Chart in Section 3.4, page 54.

2.4.6. Viewing the voltage and alarm settings

You can review the parameter settings in the AT30 charger by pressing

the

key, a different parameter displays, in the following order:

• Float voltage

• Equalize voltage

• Equalize time (in hours)

• High dc voltage alarm setting

• Low dc voltage alarm setting

• Current Limit (in Amperes)

Do not use a dc voltmeter. The ripple voltage on a battery is a very small ac voltage.
