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 DLRO100EB Digital Low Resistance Ommeter
A significant addition to the comprehensive range of Megger Low Resistance Ohmmeters, DLRO100 enables low resistance measurement, across multiple applications, in areas without access to mains power. The integral Li-Ion battery supplies a constant 100 A current for up to 200 Manual/Auto tests to enable enhanced productivity in remote locations. With a focus on user safety, advanced design features ensure the safe operation of the instrument in the most adverse conditions, including a CAT IV 600 VAC / 500 VDC safety rating in accordance with IEC61010. The rugged design, intuitive interface and IP54 (lid open) rating ensure reliability and ease of use in the most arduous of conditions.
There are three models in the series, all three models can be line powered, are rated CAT IV 600 V and can test currents from 10 to 110 A. B in the model name indicates the battery powered option (in addition to AC power).
- DLRO100 E or EB - The base model.
- DLRO100 X or XB - The mid-range model includes all features in the basic model, with added data storage and DualGround™ testing capability.
- DLRO100 H or HB - The top-of-the-line model includes features in the E and X models, with asset tagging (enter unique asset ID's using the DLRO100 Asset Tag Windows app), Bluetooth® download and USB remote operation.
Megger DLRO100EB Comes Supplied With:
- Certificate of Test
- Quick Start Guide
- Calibration Certificate
- CD Containing User Guide
- Mains Lead
A lead set is NOT included with the instrument and must be ordered as an optional accessory.
Test Modes
The Manual test mode allows the user to initiate the test procedure once the probes are in contact with the object under test. Once the TEST button is depressed the TEST lamp will illuminate and the instrument will undertake a single test to verify the resistance of the test object.
In Auto mode the user selects the desired current, connects the current test leads and as soon as the potential leads are connected a test will start automatically. To repeat a test, simply break contact with the potential probes and remake contact.
In Continuous mode the user connects the test leads and presses the TEST button, initiating the test procedure. The instrument will continue to test, updating the display after each new test cycle, until the TEST button is pressed or the test procedure times out.
Key Features:
- CAT IV 600 VAC / 500 VDC for safe operation
- Lightweight 100 A battery powered unit for portability
- High noise immunity for stable readings
- Smooth DC Output for circuit breaker testing
