1. Buy robust, good quality test equipment from a reputable supplier: reviews and online forums can help – don’t just get what’s on offer or a brand you recognise.
2. Look after your equipment: keep it in a protective case and handle it with care. Avoid storing it in very hot, cold or damp conditions.
3. Test your equipment regularly: check regularly for faults and accuracy and have it calibrated / serviced annually by an Precision Laboratory.
