Influencing quantities:
Reference conditions
Temperature
23° C ± 5° C
Relative humidity
45 % to 75 %
Power supply voltage
9 V ± 1 V
Frequency domain of the applied signal
40 Hz to 1 kHz

4.2 Specifications of the reference conditions
Uncertainties are given in:
X % of the reading (R) ± Y counts (D).
When the frequency exceeds 1 kHz, apply the formula given in the tables
X % R + Y % x [F (kHz) - 0.4] R ± D.
where:
- Reading
"R",
- Digit
"D", the measurement count equivalent to the resolution of the display range,
- Frequency
"F" in kHz.
