MULTIFUNCTION
 TechChek
Model 830
The
Technician Friendly Multifunction Calibrator with "Keep
It Simple" Controls.
Introducing the first easy-to-use multi-function calibrator.
Just turn the knob to select a function, connect it
up and start calibrating! Take the TechChek 830 to every
site. It's like bringing a cartload of test equipment
from the shop to the control room or the field. The
TechChek 830 sources and reads like a milliamp or voltage
calibrator, simulates and measures T/Cs & RTDs like
a temperature calibrator, generates and counts frequency
and Counts-Per-Minute like a frequency calibrator and
displays pressure like a precision test gauge. Troubleshooting?
It checks continuity with a beeper and measures AC line
voltage like a multimeter!
- Compact Multifunction
Calibrator —
Source and Read Milliamps, Volts, Millivolts, Six
RTD Types, Seven Thermocouple Types, Resistance and
