ACCURACY
C, G, R, L
At 1 kc: ± 0.1% ± 0.005% of full scale except on lowest R and L
ranges and highest C and Granges, where it is ±0.2% ± 0.005% of
full scale.
Additional % error terms for high frequency and large phase angle:
C and L: ( ±0.001fi, ± 0.11Jfkc ::':: 0.5/)2)'/n of measured quantity.
Rand G: (±0.002Ji, ±O.OOOOOIJZ, ±0.1Q)%ofmeasuredquantity.
Residual Terminal Impedance: H ~ 0.001 ohm, L ~ 0.15 l'h, C ~ 0.25
pf.
DC Resistance and Conductance: Same m; for I-ke measurement, except
that accuracy b limited by sensitivity at the ran~~:e extremes. Balances
to 0.1% are possible from 1 ohm to 1 megohm with the internal
supply and detector.
D (or~) of Cor L: ±0.0005 ± 5% at I kc or lower.
±0.0005fkc ± 5% above 1 kc.
Q of R or G: ±0.0005fk, ± 2%.

Internal Oscillator: 1 kc ± 1% normally supplied. Plug-in modules
for other frequencies available on request. Level control provided.
Internal AC Detector: Can be used either flat or selective at frequency
of plug-in module (normally 1 kc). Second-harmonic rejection approx-
imately 25 db; sensitivity control provided.
Internal DC Supplies: 3.5 volts, 35 volts, 350 volts, adjustable, and
power limited to less than Ya watt.
External Oscillator and Detector: For measurement at othE>r frequencies
from 20 cps to 20 kc, TYPE 1210-C Unit l{-C Oscillator, che TYPJo;
1311-A Audio Oscillator, and TYPE 1232-A Tuned Amplifier and
~ull Detector are recommended.
DC Bias: Provision is made for biasing capacitors to 500 volts with
external supplies, and for biasing current in inductors.
