SPECIFICATIONS
For convenience to the user, the pertinent specifi cations are given in a label, shown in Figure 2-3 affi xed to the
case of the instrument.
Calibration and Test Conditions:
Calibrated at 23°C, <50% RH, Traceable to SI
1 nF - 1 µF:
Units are calibrated as both 2-terminal and as
3-terminal capacitors. For 2-terminal measurements, the
LO
terminal is shorted to the
GND
terminal. The
Adjustments
to Nominal
specifi ed in the table above apply to 2-terminal
measurements.
10 µF - 1000 µF:
Units are calibrated as 5-terminal
capacitors, "series model"
Series Inductance:
for 0.01 µF - 1 µF:
typically < 0.06 µH
Series Resistance:
for 0.01 µF - 0.1µF:
0.02 Ω
for 1 µF:
0.03 Ω

† Maximum allowable Vrms; subject to maximum Vdc = 50 V and max Vrms = (39000/f) for C = 10 µF;
(26000/f) for C = 19 µF; (13000/f) for C ≤100µF, where f = frequency (in Hz).
* Initial Adjustment to nominal is only applicable when manufactured
