These would set the thing off in your pocket so you couldnt tell if the meter box was live or not

Rail firms had a similar problem with high impedance digital meters when working under 25KV. The meter would give a reading with no input connected. Solution- provide a 150kohm shunt on th meter input. But come BSI, each meter had to be equipped with it's own shunt and each calibrated as a pair.
