F. S. Brainard & Co. reserves the right to modify its designs at any time in order to
supply the best products possible. All instruments are warranted for two years from

agreements are available following the initial two year warranty period.
1.2 Meter-Master Care And Maintenance
The Model 100P requires a minimum of care and maintenance. However, as a piece of
electronic equipment powered by internal, rechargeable batteries, several points should
be kept in mind.
ÎKeep Batteries Charged. Lead-acid battery life is maximized when the batteries are
maintained in a charged condition as often as possible. Complete discharging of lead-
acid batteries can result in their permanent damage. Although the Meter-Master batteries
should last a minimum of 3 months after being fully charged, whenever possible, connect
the Meter-Master to the battery charger when the Meter-Master is connected to the
computer and always recharge the batteries after each use if time permits. Leave the
Model 100P connected to the charger whenever it is not in the field.
Because the Model 100P is built to power-down when it senses low battery power, the
batteries are protected from complete discharge during normal operation. However, after
a power-down due to low battery power, do not allow the Meter-Master to sit for more
than 7 days without recharging.
The Model 100P uses battery power whether it is recording or not. Do not store the
Meter-Master in a discharged condition unless it is connected to the battery charger.
Store the instrument either fully charged or, preferably, connected to the battery charger.
If not connected to the charger while in storage, remember to recharge the batteries at
least once each month.
A battery charger is furnished with the Meter-Master. It has been selected as optimal for
this application. Other chargers may not provide the same level of battery performance.
ÎKeep Sensor Port Clean. Before connecting hose, make sure no dirt or other debris is
lodged inside pressure connector. Flush out with water if necessary; don’t dig out with
anything sharp or hard. Keep protective cap over connector when not in use.
ÎAvoid Needless Submersions. Although the Meter-Master is sealed to resist water
intrusion, care should be taken to avoid needless submersion. If the unit is chained inside
a pit, ensure that it can float up to the top if the pit fills with water. If water accumulates
inside the unit, it should be returned to the factory for service.
ÎHandle Cables With Care. To ensure long cable life, handle cables carefully and avoid
attempting to insert a cable into the wrong receptacle on the front of the unit. Each
connector has a unique number of pins and two channel guides for proper connector
mating. Each cable should seat easily into the receptacle; never try to push or press a
cable into place. (NOTE: Although the RS232 cable and battery cable have a different
number of pins, the RS232 cable can be mistakenly plugged into the Meter-Master
battery connection. No damage will result.)
