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.

Description

MIT481 Telecoms insulation and continuity tester

The Megger MIT480 series instruments have been developed specifically for the telecommunications industry. The insulation and continuity testers combine the latest range of measurement techniques with new instrument design to provide a state-of-the-art tester that is compact and comfortable to hold. The MIT480 series directly replaces the well-established BM80 product group, given greater functionality with simplified operation and greater application range.

The range:

MIT480 50 V, 100 V tester MIT481 50 V, 100 V, 250 V, 500 V, 1000 V tester MIT485 As 481 plus downloading results

Insulation Testing:

Test voltages - 50 V/100 V or 50 V to 1000 V insulation test voltages available depending on instrument. The actual test voltage is displayed on the smaller digital readout, with the insulation result on the larger digital display.
Analogue arc - The display also features an analogue arc to replicate the response of a moving coil display.
Insulation leakage current - The MIT481 and MIT485 offer insulation leakage current display, in addition to insulation test voltage.
Insulation testing - up to 10 GΩ or 200 GΩ test range are available.
Silicone test leads - (supplied) are essential to prevent error in measurement on insulation tests of greater than 10 GΩ .
Test inhibit - prevents testing if voltages in excess of 75 V are detected when making insulation tests.
Test lock - allows the insulation test to be ‘locked’ on continuously.
Timed testing - MIT481 and MIT485 have timed insulation test options.

Continuity and Resistance:

200 mA or 20 mA - Either 200 mA or 20 mA continuity test currents are available. 20 mA test current will considerably increase battery life.
Auto test - on circuit contact enables real two handed operation without the need to press the test button.
Lead null - Lead resistance compensation (NULL) operates up to 9.99 Ω of resistance.
Buzzer ON-OFF - selected by push button.
Limit alarm - Continuity buzzer limit alarm provides adjustment of the maximum acceptable resistance. Resistance below the set limit sounds the buzzer. This is adjustable from 1 Ω to 20 Ω in 5 steps.
kΩ range - extends resistance measurement from 10 Ω to 1 MΩ.

Capacitance measurement:

Capacitance measurement - auto ranges from 0.1 nF to 10 µF. Results are displayed on the primary digital display.
Cable length - is displayed on the secondary display. Cable length is calculated from an adjustable cable capacitance reference (default 50 nF/km).
Cable capacitance reference - A variable value for distance calculation is adjustable from 40 nF/km to 60 nf/km.
km or Feet - Can be displayed, selected in set-up.

Voltage and Frequency:

CATIV - Suitable for use on circuits up to 600 V CAT IV.
AC voltage - measurement is True RMS up to 600 V.
DC Voltage - measurement to 600 V.
Fully auto-ranging - from 10 mV up to 600 V provides wide range of applications and suitable for transducer inputs
A default voltmeter - is activated on any test function if a circuit voltage is detected.

Additional Features:

All tests will be inhibited if a live circuit voltage above 75 V is detected.
Instrument fuse failure will not affect instrument safety functions.
Rubber boot combines the tough shock absorbing outer protection with excellent grip, on a strong modified ABS housing, providing an almost indestructible case.
Battery requirements are 5 AA batteries of either standard Alkaline or Nickel Metal Hydride (NiMH) rechargeable type.
Battery condition status is permanently displayed.
