Determines Conditions of Lead-acid and NiCd cells up to 7000 Ah
On-board Pass/Warning/Fail Indications
Robust Repeatable Instrument
Single and Dual Channel Measurements
On-line Testing
Checks charger condition
Stores more than 2000 sets of data
The BITE2 and BITE2P Battery Impedance Test Equipment determine the condition of lead-acid and nickel-cadmium cells up to 7000 Ah.
An advanced feature set has been developed that includes Pass/Warning/Fail calculations based on a user-entered baseline value, advanced printing functions and more.
The case of the BITE2P consists of both the transmitter and a carrying case for all of the standard accessories and some of the optional accessories, in an all-in-one unit.
The BITE2 and its accessories fit into a sturdy canvas case with a shoulder strap.
The instruments work by applying a test signal across the battery string while on-line, then calculates impedance based on simultaneous measurements of current and resulting
voltage drop of each cell. They also measure dc voltage and interconnection (strap) resistance to help determine the overall condition of the entire battery string's electrical
path from terminal plate to terminal plate.
In addition, the BITE2 and BITE2P measure ac ripple current which, if too high and over an extended period of time, can damage the battery by heating it.
(An increase of battery temperature by 18ºF/10ºC will halve the life of lead-acid batteries.) Battery manufacturers generally recommend a limit of 5A of ac ripple
current for every 100 Ah of battery capacity. The first measurement that the instruments take is ac ripple current which should be trended.
The BITE2 and BITE2P receiver stores the readings in its internal memory. These measurements, along with other maintenance data such as ambient and pilot cell temperatures
and ac ripple current, assist in determining the overall condition of battery systems. Megger recommends that impedance measurements with the BITE2 be made part of a battery
maintenance program with readings taken and recorded semi-annually for flooded batteries and quarterly for VRLA.
Unlike load cycle testing that involves substantial downtime and repeated discharges, using the instruments require no battery discharge, nor do they stress the battery in
any way compared to other techniques. With a test time of less than 15 seconds for each cell and intercell connector, one person can easily, quickly, and precisely measure
internal cell impedance, dc terminal voltage and intercell connection resistance without taking the battery system off line and evaluate charger condition also.
Naturally, everything you need to perform these tests is included with the basic instruments. There is a full line of optional accessories to enhance the capabilities of the BITE2.
The BITE2 has the ability to download to a PC for data interpretation and to PowerDB, Megger's battery database management software. Additionally, the BITE2P has a built-in
printer to review the active test and also to leave a hard copy record at the site.
Receiver
The battery-operated receiver incorporates the potential leads, clamp-on current sensor, and data storage capabilities. It stores more than 2000 sets of data
(cell impedance, cell voltage and interconnecting strap resistance, date and time stamps) in up to 300 tests. It also allows for printing the active test for
easy review and retest. Selective printing of any test and deleting oldest tests are now included features to maintain in memory the most critical tests.
At any time while performing a test, the operator can review the current test results by using arrow keys and scrolling back through the active test screen. The operator can also
print the active test using the BITE2P transmitter printer. If needed, the operator can retest any of the cells and straps in the current test. Stored data can also be
downloaded via the RS-232 connector directly to a personal computer or the BITE2P transmitter printer.
One additional feature of the receiver is that if you are called away while in the middle of the test, simply shut down the instrument and it will remember where you left off
in the test.
The clamp-on current sensor is connected to the receiver during testing and clamped around a convenient inter-tier or intercell connection within the loop created by the
transmitter's current source leads and the battery string. If the intercell or inter-tier connection consists of more cables than the diameter of the clamp-on current sensor
can encompass, the receiver has a split-strap function.
There are optional Rope CTs available for large buss work. With the optional bar-code wand, additional information such as location ID, user ID, ambient and pilot cell temperatures
can be recorded and stored. There is space on the printout to enter specific gravity readings.
