I never understood the authoritarian approach to meter backlighting with these short-duration timers. If the user wants the backlight on, turn it on - they probably have a reason. If the battery runs down, fine - the user knows that the backlight draws power.
Yep. It's ridiculous.
Put a warning sticker on the back or whatever to avoid idiots complaining about battery life, but keep it on.
(...or make it timeout by default but add a very simple way to make it stay on, eg. a long press of the power light button)
PS: The Chinese can make a set of Christmas tree lights (
hundreds of LEDs) last for weeks on a set of batteries, why can't multimeter techs do the same?
