Also, another question, regarding another instrument, an 8 Mk 6.

When measuring VDC, the displayed reading whilst increasing the voltage is different than when decreasing.

For example, when increasing voltage, the readings may be 1, 2.....7, 8v

when decreasing, there's a difference of 200mV, so 9v can be 8.8v, 7 would become 6.8v.

What would cause this do you think?

Thanks.
