Readout Modules with Peak-Hold Feature
FEATURES
For use with Vishay Measurements Group 2300 Signal
Conditioning Amplifier System
Provides real-time digital readout with peak-hold
capability
Both maximum and minimum signals are sorted
independently
Front-panel jacks are provided for utility inputs such as
the bridge excitation supplied to the signal conditioners
via the excitation monitor jacks
Contains its own power supply which utilizes line
voltage from the 2300 System Rack Adapter or
Portable Enclosure
SPECIFICATIONS
Display
LED's with
19 999 counts full scale.
Sensitivity/Resolution
1 mV per count.
Input Circuit:
Amplifier Configuration: Single-ended floating common.
Input Impedance: 2M
nominal.
Rear Connectors: 8 channels BNC.
Front Connections: 1 channel, standard banana jacks.
Input Selection: 9-position switch.
Peak Retention Capability
Both positive-going (MAX) and negative-going (MIN) peaks
are stored in two separate circuits independent of DISPLAY
MODE selection. (The storage capability is always active.)
Display Modes:
Track: Display follows input voltage.
Peak-Hold: Displays one of the stored peak values.
MAX: Selects the MAX stored value.
MIN: Selects the MIN stored value.
Accuracy
Step Input:
0.1%
4 counts for step input up to 15V >4
msec duration.
Repetitive Step Input:
0.1%
4 counts for repetitive step
inputs of >300 msec duration.
Minimum number of steps required: 4 msec
pulse duration.
Repetitive Sine Wave:
5%
4 counts for repetitive sine wave input of <1000 Hz.
0.5%
4 counts for repetitive sine wave input of <100 Hz.
Hold Stability
<1 count/minute typical, 2 counts/minute maximum
averaged over 5-minute period.
Reset Capability
Manual or automatic timed reset of MAX and MIN peaks.
Optoisolator input requires 2 to 30V (<5 mA @ 5V) for 0.1
msec minimum.
Power
115/230 Vac, 50-60 Hz, 10W max.
Size & Weight
8.75 H x 3.44 W x 17.56 D in [222.2 x 87.5 x 446 mm];
4.8 lb [2.2 kg].
All specifications are nominal or typical at +23
C unless
noted.
