POWER
The M5000 can be powered with:
• Battery only (2 D-cells or 4 D-cells)
• 100…240V AC (with battery back-up)
• 9…36V DC (with battery back-up)
Battery
Use a two D-cell battery pack for sizes 1/2…6 in. (DN 15…150) or a double two D-cell battery pack for sizes 8…24 in. (DN
200…600). For backup battery options, see "Battery Backup" on page18.
The meter is delivered with the battery unplugged. It must be plugged in before using the meter. The connection jack is
located by the symbol "BAT“ on the board.

Battery Life
OTE: N The battery life strongly depends on ambient temperature, sampling rate and the number of outputs used.
Standard Battery Pack
Sampling Expected Life
1 s 8 months
4 s 2.7 years
8 s 5.3 years
15 s 10 years
These calculations are for a standard battery pack, with two D-size batteries, with communication and outputs OFF, at a
temperature of 77º F (25º C). See "Battery Level Indicators" on page25.
Battery Replacement
1. Go to Main Menu > Misc > Battery > Change and select the capacity of the battery pack to be installed (see label on the
battery pack 19 Ah, 38 Ah or 70 Ah). Press E to quit. The display freezes (no reaction by pressing any button).
2. Open the cover.
3. Remove all connectors (detector and outputs).
4. Remove all 4 screws of the main board, remove the circuit board and disconnect the old battery.
5. Remove the old battery and wait about 2 minutes before replacing it with a new one (LCD display should be o).
6. Plug the battery connector into the back of the main board and reinstall the circuit board.
7. Replace all the plugs.
8. Close the cover tight.
9. Check time and date (Main Menu > Misc > Time and Main Menu > Misc > Date DMY).
10. Check capacity of battery (Main Menu > Misc > Battery AH). The rst value is the used capacity, which should be 0.0. The
second value is the capacity of the battery pack. Battery AH is a read-only parameter.
OTE: N Totalizers and configuration remain unaffected during battery replacement.
