Information on the calibration of newly purchased equipment and what it means to you.
Calibration and its certification comes in varying forms on new equipment and in this section, we will break it down into the three areas that we use to classify calibration state at the point of purchase.
Manufacturers Calibration Certificate
This is a calibration certificate offered by the manufacturer supplied with the tester. This is also known as an end-of-line certificate or manufacturer’s certificate. These certificates vary depending on the manufacturer and product. They will not have your company's name on them and don’t always show proven test results.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
This instrument comes complete with the manufacturer's calibration certificate. Please be aware that these certificates are generic and may also be time-lapsed.
If you would prefer a personalised full traceable calibration certificate applied to the equipment before dispatch, then please select this option from the drop-down menu above, an additional calibration charge will apply.Manufacturers Certificate of Conformity
A manufacturer's certificate of conformity is not a calibration certificate. It is merely a statement that the equipment has been produced to operate within its intended application, it has no traceable certificate or constitutes any defined results for accuracy before leaving the manufacturing process.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
This instrument comes with a ‘manufacturer's certificate of conformity’. It is important to understand that this does NOT constitute a ‘calibration certificate’. A certificate of conformity merely states that the equipment has been designed and produced to meet the requirements of its intended application.
Where calibration of an instrument is possible we will offer this as a separately purchasable item and may be selected from the drop-down box above. You will be sent a full traceable calibration certificate produced in our laboratory and applied with your details as required.Personalised traceable calibration certificate from isswww
This is a calibration certificate created by us at ISS. This certificate is fully traceable to national and international standards. The certificate will show your company's details, tester information, proven test results and the equipment used to carry out the test. Nearly 90% of all calibrations we do are done in-house in one of our many fully equipped laboratories. You can add this service to your order on the product page before you checkout.
Where applicable we will include the following statement relating to the item/s on the products page under the heading *Important Calibration Information.
We are on occasion able to offer FREE calibration on certain products at their point of sale (newly purchased equipment only) please look out for the following badge on the product's page to take advantage of this free offer.

Megger LTW315 Earth Loop Tester
The entry-level tester in Megger's earth loop tester range, the LTW315 is used for carrying out 2 wire loop impedance measurements on phase to earth or phase to neutral.
Guaranteed not to trip working RCDs of more than 30mA thanks to a non-trip loop test and compatible with both three and single phase systems, this tester makes performing measurements easier by requiring the use of only 2 test leads in order to carry out measurement procedures. When there is no risk of tripping an RCD it is also possible to use high current loop testing mode.
When carrying out no-trip testing procedures the LTW315 constantly evaluates the level of noise detected on circuitry to ensure that the accuracy of results is not modified by the presence of electrical noise.
The Megger LTW315 is part of the LTW range of earth loop testers. The following table outlines the difference between each of the available models in this series.
Megger LTW315 Comes Supplied With:
- Megger LTW315 Earth Loop Tester
- BS1363 to 3 x 4mm Socket Leadset
- 2 Wire Leadset with Croc Clips
- Shuko Plug Test Lead – EU-SC
- AU/NZ Plug Test Lead – EU-AU
- Hard Carry Case
- User CD
Key Features:
- 2-wire loop testing procedures on phase to earth and phase to neutral
- Guaranteed to not trip out RCDs thanks to non-trip loop testing
- Noise detection filters out electrical noise that can create erratic readings
- Resolution down to 0.01Ω
- Portable lightweight instrument with tough carrying case encasing the tester
- AUTO start function starts testing as soon as the leads are connected
- PFC display up to 20kA
