Fluke Corporation 8508A Extended Specifications
15
Notes:
[1] Specifications apply for max resolution in each function, normal mode
[2] Assumes 4 hour warm-up period
[3] Input zero or offset null required whenever the temperature moves more than ±1 °C from the temperature at which the
previous null/zero was performed
[4] TCal = Ambient calibration temperature
[5] Integration time > 1 Power Line cycle
[6] Valid for signals >1 % Full Scale, Transfer Mode On. Signal must be DC coupled <40 Hz. Readings invalid with Transfer Mode
On and 1 Hz filter selected when using internal trigger mode
[7] Max Volt.Hertz 3 x 10 7
[8] >300 V, <10 kHz add: ±0.0004 (R-300)
2
ppm
>300 V, 10 kHz - 30 kHz add: ± (0.0004 + (F - 10000)*1E-7)*(R-300) 2 ppm
>300 V, >30 kHz add: ±0.0024 (R-300) 2 ppm
[9] Typical below 10 Hz for ACV, below 10 Hz, and above 10 kHz for ACI and above 2 G
Ω
for Resistance
[10] Tru Ohms mode available on 2 Ω to 20 k Ω ranges. Read Rate reduced in Tru Ohms mode. Specification for Tru Ohms same as
corresponding Normal or Lo Current range.
