Excerpts from the Instruction manual
DC1 Setup
The meter provides setup settings for each battery. To access these settings, first go to the Setup menu. Scroll to the desired battery label followed by Setup (such as DC1 Setup) and then press Select. NOTE: some settings may not be available for all batteries. The battery setup settings are described below. To make a change, scroll to setting and press Enter. Press the LEFT ? or RIGHT ? arrow buttons to view the available setting options. Press Enter to save the setting. Press Cancel to cancel a change.
Enable
To display the battery and its measurements, change this setting to ON. If enable is OFF, he battery along with its measured values will not be displayed.
Set State-of-Charge (SoC) to FULL (1830 Only)
When this option is selected, the meter will consider the battery's present State-of-Charge to be FULL. To do this, scroll to Ok and press Select. The screen will then return to the meter summary display.
Battery Voltage (1830 Only)
This setting indicates the nominal voltage of the battery. The options are 12V, 24V, 36V, & 48V.
Bat. Type (1830 Only)
This setting indicates the battery type. The available options are listed below:
FLStd - Standard Flooded Lead Acid Batteries
AGM - Standard Absorbed Glass Mat (AGM) Batteries
TPPL - Thin Plate Pure Lead AGM Batteries
GEL - Gel Batteries
FLRsv - Flooded Acid Reserve. Premium Flooded Lead Acid Batteries such as Rolls.
FLLoM - Flooded Low Maintenance. Sealed Flooded Lead Acid Batteries
Bat. Capacity (PN 1830 Only)
This setting indicates the capacity of the battery in Amp-hours. The available range is 0A to 5000A. 14
Full Chrg Volts (PN 1830 Only)
This setting indicates the voltage at which the battery is considered to be fully charged. The available range is 0.1 V to 70.0V. This should be set to the absorption voltage of your charger. If you don't know the absorption voltage, you can figure the absorption voltage out by observing the output voltage of the charger once it enters the absorption phase. If you have multiple charging sources, set it to the higher absorption voltage. In extremely hot or cold temperatures the absorption voltage will need to be set slightly higher (for cold) or slightly lower (for hot).
Example 1.
In Blue Seas Systems P12 Charger this parameter is called the Absorb Voltage. For lead acid values, the default value is 14.5 V DC. So in the M2 the Full Chrg Volts setting would be set slightly smaller than the 14.5 V (14.4 V).
Example 2.
An unknown 10 A charger is connected to a partially discharged battery. Initially the meter should read approximately 10 A of charging current with the voltage increasing over time. At some point (around 14.5-14.8 V DC) the voltage should stabilize and the charging current will start decreasing. This voltage is the Full Charge Voltage. Set the Full Chrg Volts to 0.1 V below the observed voltage.
Full Chrg Amps (1830 Only)
In addition to Voltage, the user can set the Charging Current at which the battery is considered fully charged. The value is a percentage between 0.0 % and 10.0 % of the battery's set Amp-hour capacity. This value should be set to 0.2% higher than the End of Absorption Amps. That is the current where the battery charger switches from Absorb to Float stage. Values are typically 2% for AGM and 3% for Lead Acid. As a battery ages, this percentage may need to be increased.
Charge Eff. (1830 Only)
This setting is for indicating the battery's percent charge efficiency. The value may be set between 0% and 100%. The user can adjust the charge efficiency up or down depending on the age and/or type of battery that they are using. AGM Batteries tend to be much more efficient that Lead Acid Batteries. If the M2 meter indicates 100% before the charger is done with its bulk charge then the efficiency is likely to high. Try decreasing it a couple of percent. If the M2 meter never indicates full charge then efficiency is likely to low. Try increasing it a couple of percent.
Shunt Value (1830, 1834 Only)
The M2 is shipped with a single 500A/50mV shunt (the ratio is 10000:1). The shunt value assumes that the full scale shunt output voltage is 50 mV. To use a shunt with a smaller output voltage use the following formula: Shunt Value = (New Shunt Ratio) / 20. For example to use a 400A/20mV shunt (Note: 20mV = 0.02V), you would set Shunt Value to (400A/0.02) /20 = 1000A.
Zero Shunt (1830, 1834 Only)
Menu->Setup->DC1 Setup->Zero Shunt. To zero out the shunt, connect both of the current sense wires to the negative bus bar side of the shunt. Then press the Reset button on the M2 Meter to confirm the action.
State of Charge(SoC) Cycles (1830 Only)
Menu->Setup->DC1 Setup->SoC Cycles. The SoC Cycles option allows the user to reset the battery's recorded SoC cycles to 0. To do this, scroll to and press Select on SoC Cycles. Text will appear asking to confirm or cancel the reset request. Press Yes to confirm or No to cancel the action. NOTE: This function does not work in Version 1 of the Firmware.
State of Charge(SoC) Default Settings
To reset the battery's State-of-Charge settings to the default values, press Select on SoC Defaults. Text will then appear asking to confirm or cancel the reset request. Press Yes to confirm or No to cancel. The following changes will occur after a reset: 1. SOC Cycles will be reset to 0 2. State of Charge is Reset to 98%
