CALIBRATION:
The LT-952 should be re-calibrated annually under normal circumstances and usage. It should also be re-
calibrated if it exhibits inconsistent, unexpected, or ambiguous behavior. There are no user-available
adjustment means; it must be returned to a competent and qualified calibration lab for service.
The international standard ISO/IEC 17025 lists requirements that testing and calibration laboratories must
meet if they wish to demonstrate that they operate a management system, are technically competent, and
are able to generate technically valid results. The exclusive use of calibration service providers which have
been recognized by an independent accreditation body as conforming to the requirements of ISO/IEC
17025, and whose scope of accreditation encompasses leakage current testers, is the most reliable way to
ensure that your test device continues to meet the requirements of the standard and is strongly
recommended. ED&D offers calibration services that meet these requirements. Please contact us to
arrange for service.
The recommended calibration intervals are as follows:
6 Months - If the LT-952 is being used in an environment where it is subject to vibration and frequent
changes in temperature (i.e. Field Testing).
12 Months - If the LT-952 is being used in a laboratory or production setting with a controlled environment.
