Temperature effect :

The variation of indication caused by effects of temperature is to be

calculated by below formula; which is to be added in the specified

accuracy while measurement :- Formula : ± 0.08 x (t2 - t1) % of F. S.

where t1 = reference temperature (+20°C) and t2 = ambient

temperature in °C.
