4.1 Reference conditions
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
Absence of electric field
NB: below, the accuracy is given as X % of the reading (R) ± Y counts (D). When the frequency exceeds 1 kHz, apply the
formula X % R + Y % x [F (kHz) - 1] R ± D
with F in 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.
4.2.1 DC voltages
60 mV range
: The measurement of high currents or over a long period can cause certain components to heat. In this case,
a certain waiting time is needed to return to the specified metrological conditions. It is possible to check whether the offset
has returned to an acceptable value by short-circuiting the "+" and COM terminals. A reading of < 5 D should be obtained.
