4100 SERIES CLOCK DRIVER CARDS:
4100-C:
A separate clock driver card is required to drive 1 or more amplifier cards. This unit indicates the "on" condition of the ±15 volts DC supply voltage with individual red LED lights and has a x3 amplitude drive adjustment pot for supplying a 15kHz excitation signal. This control is used to match a required calibration sensitivity to a specific model displacement probe. (1 clock, 0.80" wide normally fits in a far right rack slot).
4100-CM3-4.5 LED:
The same as the 4100-C, except that a larger, 2.8" inch wide, front panel has been added to accommodate a standard 31/2 digit LED meter with a multi channel selector switch. An optional 41/2 digit LED meter may be specified. The meter normally reads percent of full scale (i.e. 100.0) or can optionally read in volts DC (i.e. 10.00). (2 slots plus a clock card slot.)
NOTE:
- Instrumentation amplifiers come standard with 232Hz, -3dB frequency response with 18dB/octave roll-off. Specify options: -WB with 3.1kHz, -3dB or -5WB with 5.0kHz, -3dB.
- An additional x1 to x6 screwdriver adjustable amplitude control is provided standard on 4100-S, SL, and -L to have a total of 3 x 6 = 18 V P-P drive amplitude capability.
- Model 4100-SL and -L amplifiers have A + B /A - B sums amplifier standard. Consult factory.
