Why is the AMPTEC 620A-4 fail safe Ohmmeter/Igniter Tester safer than a DMM?

The AMPTEC 620A-4 is not a commercial DMM (most DMMs measure AC Voltage – 5 ranges, DC Voltage -6 ranges, AC Current -5 ranges, DC Current – 5 ranges, frequency , multiple 5 ½ or 6 ½ digit resolution modes, front and rear input switches etc.) Some DMMs are even AC line powered (i.e. 120 VAC 60 Hz). An AC powered DMM can be very hazardous/dangerous to use when checking explosive squib resistances for many reasons. Most DMMs also do not have a insulating polyurethane PCB conformal coating (see below) or USAF Munition Safety Board Approval for use on explosive ordnance. All commercial DMMs lack a host of safety features offered by all AMPTEC RESEARCH’s Explosive Safety Test Instrumentation – The AMPTEC 620A description below is just the tip of the iceberg. The AMPTEC 620A’s one measurement function is resistance, which makes for less operator error than a typical 14 button multi-function digital multimeter. The 620A is completely battery powered (total power line isolation), when charging
