1. For extended use at high RH, change the 400 mV and 4.0 V ac accuracy specification to ± (1.5 % + 4 counts) for 45
Hz to 1 kHz and ± (3.0 % + 25 counts) for 5 kHz to 20 kHz.
2. Below 10 % of range, add 6 counts.
3. Models 85 and 87 are true rms responding Meters. When the input leads are shorted together in the ac functions,
the Meters display a reading (typically <25 counts) caused by internal amplifier noise. The accuracy on Models 85
and 87 is not significantly affected by this internal offset when measuring inputs that are within 5 % to 100 % of the
selected range. When the rms value of the two values (5 % of range and internal offset) is calculated, the effect is
minimal as shown in the following example where 20.0 = 5 % of 400 mV range, and 2.5 is the internal offset: RMS =
SQRT[(20.0)

+ (2.5)

] = 20.16. If you use the REL function to zero the display when using the ac functions, a
constant error that is equal to the internal offset will result.
4. Frequency range: 1 kHz to 2.5 kHz.
5. Below 10 % of range, add 16 counts.
