Detail Produk
The 741B is easy to use with flexible test strategies. And like all Fluke tools, it's rugged, reliable and tough as nails. It's like having several powerful tools in one - so you can work faster than ever:
- Measure volts, mA, RTDs, thermocouples, frequency, and ohms to test sensors, transmitters and other instruments
- Source/simulate volts, mA, thermocouples , RTDs, frequency, ohms, and pressure to calibrate transmitters
- Power transmitters during test using loop supply with simultaneous mA measurement
- Measure/source pressure using any of 29 Fluke 700Pxx Pressure Modules
- Measure and source simultaneously with one compact, rugged, reliable tool
- Create and run automated as-found/as-left procedures to satisfy quality programs or regulations. Record and document results
- Use many features like autostep, custom units, user entered values during test, one-point and two-point switch testing, square root DP flow testing, programmable measurement delay etc.
- Easy to use
- Three year warranty
- Bright white display. Read both sourced and measured parameters.
- Multi lingual interface
- Handling of fast pulsed RTD transmitters and PLCs, with pulses as short as 1msec.

90 day specifications |
|
The standard specification intervals for the 741B is 1 and 2 years. |
|
Typical 90 day measurement and source accuracy can be estimated by |
|
dividing the one year "% of reading" or "%of output" specifications by 2. |
|
Floor specifications, expressed as "% of full scale" or |
|
"counts" or "ohms" remain constant. |
