Test Frequency: 1 kHz ± 1%.
Unknown Excitation: The 1 kHz voltage (Vx) and current (Ix) levels listed in Table 1-1 are held
constant by an internal amplitude control circuit.
Measurement Rate: Four per second; one second is required for first reading after connecting
unknown to terminals.
Measurement Display: 3½ digit LED with decimal point. Blanked for overload conditions.
Unit Display: Unit of mesurement being displayed by the LED readout is indicated by
position of the range switch, used in conjunction with the desired function
button and the front panel range scale.
External Bias: Rear panel terminals are provided for connection of external supply. 0 V to
50 VDC, 0.1 A maximum. (Read Section 2.3.6 before using external bias.)
Static Charge Protection: Diode and resistor discharge network.
Connection to Unknown: Four-terminal, shielded, connections are provided by the KELVIN KLIPS®
cable assembly (TEGAM Part No. #CA-162-36) supplied with the Model 253.
Outputs: Analog signals of 1 V per 1,000 counts, 1 kΩ source resistance is available
at rear panel.
L, C, R, or G, with simultaneous output of D for L or C.
