BITE2 and 2P
Battery Impedance Test Equipment
Determines condition of lead-acid and NiCd cells up to 7000 Ah
On-board Pass/Warning/Fail indications
Robust, repeatable instruments
On-line testing
The BITE 2 and BITE 2P 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 BITE 2P 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 BITE 2 and its accessories fit into a sturdy canvas case with a shoulder strap.
The instruments work by applying a test current across the battery string while on-line, then measuring the total current (ac ripple + test current) and the voltage drop of each cell/jar. It then calculates the impedance. 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.
The BITE 2 and BITE 2P 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 BITE 2 or BITE 2P be made part of a battery maintenance program with readings taken and recorded semiannually 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 20 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.
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 BITE 2 and BITE 2P. Both have the ability to download to a PC for data interpretation. Additionally, the BITE 2P has a built-in printer to review the active test but also to leave a hard copy record at the site.
Megger BITE3
Battery Impedance Test Equipment
Determines health of lead-acid cells up to 2000 Ah
On-line testing with Pass/Warning/Fail calculations
Measures impedance, interconnection resistance and cell voltage
Windows CE operating system with 32 MB of memory
Measures float and ripple currents
Includes ProActiv Database Management Software
The Megger BITE3 determines the health of lead-acid cells up to 2000 Ah by taking measurements of the most important battery parameters.
The BITE3 measures cell impedance, an internal ohmic test, cell voltage, intercell connection resistance and ripple current.
For the first time in a battery instrument, the BITE3 measures float current and the harmonic content of the ripple current. There is even a built-in spectrum analyzer to show the harmonic content of the ripple current. It has firmware that can be upgraded through the Internet and supports multiple languages.
BITE Receiver
Battery Impedance Test Equipment Receiver
Used with the original BITE
Provides data storage capabilities
Measures impedance and dc voltage for lead- acid and nickel-cadmium cells
The BITE Receiver is a direct replacement for the standard receiver supplied with the original BITE. It provides data storage capabilities without having to replace the BITE transmitter.
The receiver incorporates the potential leads, clamp-on current sensor, and data storage capabilities in one unit. The unit stores more than 2000 sets of data (cell impedance, cell voltage and interconnecting strap resistance).
At any time during a test, the operator can review the current test results by using arrow keys and scrolling back through the active test screen. If needed, the operator can retest any of the cells and straps in the current test.
Stored data also can be downloaded via the RS-232 connector directly to a personal computer.
BITE ACCESSORIES

Enhances the Capabilities of the BITE line
Full Line of Accessories
Designed for Unique Situations
Great for Non-standard Installations
Megger offers a complete line of accessories to enhance the capabilities of the BITE product line. Many are shown in the Data Sheet link above, but there are many others including extension cables, calibration shunts, etc. Even though we have many accessories, we are continually evaluating additional products as interest arises.
BATTERY GROUND FAULT TRACER
Battery Test Equipment
Ground faults in ungrounded dc battery
systems easily located
Operates in high electrical noise environment
Simplifies fault tracing by identifying fault characteristic (resistive and capacitive) magnitudes
The Battery Ground-Fault Tracer is an economical, manually-balanced instrument that identifies, tracks and locates ground faults in ungrounded dc battery systems - on-line. It is particularly effective in a high electrical noise environments, as the strength of the test current can be adjusted.
The Battery Ground-Fault Tracer accelerates fault location by eliminating trial-and-error procedures and because faults can be located without going off-line. It is particularly useful in any industry where supply of power for operating measurement, communication and control equipment is critical.
BATTERY GROUND-FAULT LOCATOR
Battery Test Equipment
Ground faults in ungrounded dc battery
systems easily located
Operates in high electrical noise environment
Simplifies fault tracing by identifying fault characteristic
(resistive and capacitive) magnitudes
This instrument was developed to detect, track and locate ground faults on battery systems - without resorting to sectionalizing! Model BGL tracks and locates ground faults on live or dead battery systems. To save hours of unnecessary troubleshooting, the BGL readily differentiates between the resistive fault currents and capacitive charging currents. This feature allows the instrument to detect and track leakage paths, even in the presence of surge-suppression capacitors.
Battery Database Management Software
Organizes and manages battery data
Performs trending analysis
Assists the user to manage multiple batteries
Prints basic reports
The first of its kind, ProActiv is a powerful, easy to use battery database management software designed to analyze each individual battery in a battery system.
Battery testing is crucial to ensure a battery system provides standby and emergency power to operate devices such as emergency lighting, UPSs, operating controls, switchgear components, protective relays and continuous process systems. Failure of a battery system within environments such as utilities, hospitals or manufacturing plants can result in operational failure of the devices connected to it. ProActiv assists the user to avoid battery failures, budget for future battery string and cell replacements, and plan battery changeouts in an orderly manner.
ProActiv utilizes a standard MS Access database format. It allows the user to organize and manage battery data such as voltages, impedance, intercell connection resistance, ripple current, specific gravity, IR thermographs and more.
