Readout Modules with Peak-Hold Feature
FEATURES For use with Vishay Micro-Measurements 2200 Signal
Conditioning Amplifier System Provides real-time digital readout with peak-hold
capability Both maximum and minimum signals are stored
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 2200 System Rack Adapter or
Portable Enclosure
DisplayLED’s with ±19 999 counts full scale.
Sensitivity/Resolution1 mV per count.
Input Circuit:Amplifier Configuration: Single-ended floating common.
Input Impedance: 2MΩ nominal.
Rear Connectors: 8 channels via two INPUT connectors on
the 2250 Rack Adapter or 2260 Portable Enclosure.
Front Connections: 1 channel, standard banana jacks.
Input Selection: 9-position switch.
Peak Retention CapabilityBoth 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.
AccuracyStep 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 µsec 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 CapabilityManual or automatic timed reset of MAX and MIN peaks.
Optoisolator input requires 2 to 30V (<5 mA @ 5V) for 0.1
msec minimum.
Power115/230 Vac, 50-60 Hz, 10W max.
Size & Weight7H x 3.44 W x 17.88 D [178 x 87.5 x 454 mm];
4.4 lb [2.0 kg].
All specifications are nominal or typical at +23°C unless
noted.
