My first Nixie based instrument at work

Since the Philips PM2422A instrument works, it has been put into use. Here it is measuring a 1% (vintage) 10.7 Mohm resistor.

The reading has been jumping between 10.71 and 10.70, and finally settled on the latter value. I wonder if there is a warm up time for these instruments?!

The picture also shows the emulated "1" leftmost symbol.
