Vishay Micro-Measurements
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: 2MΩ 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.
