Time Electronics 7000 RTD Temperature Calibrator

Description

The Time 7000 is a portable RTD temperature calibration device that includes both a precision digital thermometer and an RTD/ohms calibrator. It is suitable for use absolutely everywhere due to its ability to be powered by the mains or by rechargeable batteries, making the 7000 an ideal product for laboratory, workshop or field usage.

This calibration unit can be used to check a total of 7 different RTD types, including PT100. It utilises two modes - monitoring and simulation - to provide several different values. The monitor mode on the 7000 includes the ability to check RTD probes by measuring resistance at known temperatures, measures resistance values, indicates temperature when connected to an RTD probe and can be pre-programmed with RTD characteristics for high accuracy.

The simulation mode of the Time 7000 calibrator allows output of resistance at a precise known value, simulation of an RTD value from an RTD table chart, simulation of an RTD value using the internal table and also includes specific RTD programming as well.

Additional functions of this calibrator includes 2, 3 and 4 wire connections, Celsius, Kelvin, Fahrenheit and Ohm measurements, ramp and step functions and 24 hour battery life.

The 7000 may be used with a calibrated and certified probe to produce a highly accurate thermometer.
The performance can be further enhanced by programming the actual characteristic of the probe into the unit.

Simulator Mode (4 wire)

Typical Functions	1. Output resistance of precise known value. 2. Simulate an RTD value from an RTD table chart. 3. Simulate an RTD value using the internal table.
Excitation current	0.6mA to 1mA
Resistance range	0.01Ω to 2.6kΩ
Resolution	0.01Ω
Accuracy	See specifications below
Auto re-calibration	Every 0.6 secs.
Temperature stability	Better than 0.0015% per °C

Enhanced performance may be achieved by programming the unit to simulate the characteristic of a particular probe.
Five fixed step points (0, 25, 50, 75, 100%) are available between a user set minimum (0%) and a maximum (100%).
Programmable ramp function is also available.
