Low Voltage Directive (Safety)

In order to comply with the European Low Voltage Directive (73/23/EEC), Hart Scien-
tific equipment has been designed to meet the IEC 1010-1 (EN 61010-1) and the IEC
1010-2-010 (EN 61010-2-010) standards.

10.4 Frequently Asked Questions

10.4.1

Battery

1. What type of batteries does the Model 1529 use? The Model 1529 uses a built-
in Nickel-Metal-Hydride battery pack.
2. How long do I need to charge the battery initially? The batteries come fully
charged. If for some reason they are not fully charged, the front panel indicator
shows this and you can recharge them as needed.
3. How long does the battery take to fully charge? About 3 hours from fully
discharged.
4. How long does the battery last from full charge? About 8 hours from full
charge with the backlight off.
5. How do I know when the battery is at full charge? The charging indicator LED
located on the back panel displays amber while charging and then turns green
when the batteries are fully charged (only when the AC adapter is connected).
The front panel indicator at the bottom right shows when the batteries are in use
and their approximate charge state.
6. How does the backlight affect the battery life? With the backlight on low the
battery life is reduced by 25%, medium by 30%, and high by 40%.
7. Do I have to let the battery fully discharge before charging? No, the batteries
do not need to be fully discharged before recharging. You may recharge them at
any time.
8. Is it recommended that I allow the battery pack to fully discharge occasionally?
In order to maintain the charge/discharge characteristics of the battery, Hart
recommends that you allow the battery to discharge completely once a month.
You do this by allowing the Model 1529 to operate on battery power until it
shuts down on its own.
9. If I allow the battery pack to fully discharge, what happens to the calibration
parameters stored in the Model 1529? Parameters used by the Model 1529 are
stored in non-volatile RAM (NVRAM). This IC stores the parameters even
when power is not applied.
10. How many recharge cycles is the battery good for? Approximately 500.
