 - What should I do when a "System Noise" message appears?
| | Verify that all vehicle accessory loads are off and the ignition is in the off position. The tester retests automatically when it no longer detects system noise. If the "System Noise" message continues after several attempts, disconnect the battery cables and retest. If none of the above work, please contact Customer Service. |
|
|
- What should I do when a "Check Connection" message appears?
| | The cable set may be damaged. If your tester has removable cables, call Customer Service to inquire where to purchase a set. If your tester does not have removable cables, Midtronics will repair it at the factory. Call Customer Service for a Return Authorization Number. |

- Can the Midtronics testers test a 24 Volt system? A 48 Volt system?
| | Yes. Midtronics standard testers will test any batteries as long as the system can be tested at the 16-volt level or less. The system voltage is not as relevant as is the lowest battery terminal voltage that can be safely accessed. Midtronics testers are designed to test batteries/cells for lead/acid batteries with anywhere from 1 to 8 cells. That is a nominal 2 Volts up to a nominal 16 Volts. Some cabinet/battery designs limit or restrict access to the individual batteries. Midtronics recommends testing the smallest battery segment possible. |

- My company does a yearly calibration of our instruments. Can I get a calibration procedure for my Midtronics analyzer?
| Periodic calibration of Midtronics testers is not required, as an on-board calibration function is executed prior to each battery test. It is still advisable to return the tester to Midtronics every 24 months to ensure proper operation. Due to the advanced technology of the testers, coupled with the proprietary nature of Midtronics' patented conductance technology, calibration for your tester can only be performed by an authorized Midtronics calibration specialist at Midtronics corporate headquarters. Should your Midtronics battery conductance tester require calibration, contact Midtronics for a Return Authorization number.
If you have a unique requirement for periodic calibration of test equipment, we will try our best to accommodate your specific needs. If a Certificate of Calibration is required, or if a representative of your company must be present to observe the calibration, please advise Midtronics when you obtain your Return Authorization Number (RA#). There is an additional charge for a Certificate of Calibration and/or any attended calibration visits or other custom services. Contact Midtronics Customer Service for current schedule and pricing details. |

- I used to test batteries with an impedance tester. Can I convert those reference numbers to conductance reference numbers?
| | No, they cannot be directly calculated to each other. Midtronics testers measure the conductance as an AC function. Impedance meters use a pulsed load and calculate the resistance based on the step change in the current when the load is pulsed. Conductance is also an AC test. However, conductance testers look at the "real" part of the complex admittance, called Conductance or sometimes acceptance. These techniques are interrelated, but they are not identical. Additionally, different manufacturers take measurements using different frequencies. |
|
|
- Can I get longer cables?
| | The tester cables are fixed at the current length to ensure that the cable wiring does not skew the electronic measurements. The DB9 connector contains a calibration shunt that "zeros" out any interference in the conductance measurements. Any change or alteration to the cable assembly or length would interfere with the accuracy of the measurement. |
