Product Details

This dual channel AC or DC Indicator Model 7541 advanced instruments provide engineering unit display of a strain gauge (mV/V) input and a frequency input.

The AC or DC Indicator can have 1 or 2 channel input for greater flexibility and can be calibrated in 2 direction for example clockwise and counter-clockwise or tension and compression.

The AC or DC Indicator can be used with 80 ohm to 2K ohm transducers, either directly wired or transformer coupled. In addition, 4, 6, or 7 wire circuits are accommodated.

It also computes power and carries out 21 functions including limit checks, tare, hold and max/min capture. 

The display itself is a back-lit LCD display with adjustable contrast for tailored viewing, with 16 alphanumeric characters.

The alphanumeric readout can display measured and computed data, units of measure and test status. During setup, it guides you with English language prompts. There are no manual adjustments. To calibrate, enter the full scale value in engineering units and auto-cal takes over.

The dual channel AC or DC Indicator gives a high 0.01% resolution and ±5 V and/or ±10 V analog outputs at full scale. The keyboard accesses measured data, held data, max/min data, data spread, limit status and/or I/O status without test disruption. Password protection may be used if needed.
