Test Meter PRO TMPSI3 LCD Safe Isolation Kit

Test Meter PRO TMPSI3 LCD Safe Isolation Kit

The Test Meter PRO TMPSI3 LCD Safe Isolation Kit provides electricians with a complete solution for carrying out recognised safe isolation procedures using the prove-test-prove method. Combining the TMP950 LCD Two-Pole Voltage & Continuity Tester with the TMP690 690V Proving Unit and protective Safe Isolation Kit Case, it provides the essential equipment required to verify voltage presence and absence before electrical work begins.

The TMP950 provides 12–690V AC/DC voltage testing with both LED and LCD indication, giving the user a clear digital voltage reading alongside conventional visual status indication. Its IEC 61243-3 compliance, CAT IV safety rating and IP64 protection make it well suited to professional electrical installation, inspection and maintenance work.

The TMP690 provides a portable 690V AC proving source for confirming correct tester operation before and after testing, removing the need to rely on access to a known live supply. Together, the TMP950 and TMP690 support the recognised prove-test-prove procedure used during safe isolation.

Part number: TMPSI3

Frequently Asked Questions

What is the difference between the TMPSI1 and TMPSI3?
 The TMPSI3 replaces the TMP900 voltage tester with the TMP950, adding a digital LCD voltage display while retaining the TMP690 proving unit and protective case.

Why use a proving unit during safe isolation?
A proving unit confirms that the voltage tester is functioning correctly both before and after testing for dead, supporting the recognised prove-test-prove procedure.

Does the TMP950 display the actual voltage?
Yes. The TMP950 provides an LCD voltage reading alongside LED indication across its 12–690V AC/DC range.

Does this kit include lock-off equipment?
No. For the same LCD tester and proving unit with lock-off devices and warning tags included, choose the TMPSI4.
