Features:
CA101 thermal signal checking instrument is mainly for industrial field thermal meter and designed system check maintenance, instrument to provide complete and practical function, the operation is simple.Instrument USES the single chip as the CPU, integrates the latest large-scale digital conversion IC and LCD display technology into an organic whole, with output, measurement, manual and 24 VDC power distribution function, and the four functions can work at the same time, with the screen output and the measured values and the corresponding ITS - 90 standard (thermal resistance and thermocouple).Rechargeable batteries and equipped with large capacity, easy to carry and can be easily completed industrial field thermal meter (sensor, transducer and display instrument and control system) of the maintenance, calibration.The use of it has the following features:
S small, portable and handheld.
S strong, reliable, on the back of the racks and hook hole is suitable for field use.
S big display, measurement, output can be displayed at the same time.
S of voltage, current, resistance measurement and the voltage and current output.
S eight kinds of thermocouple (T, J, K, E, S, R, N, B) measurement and output, two kinds of thermal resistance (PT100, Cu50) measurement.
S thermocouple, heat resistance measurement output has ITS - 90 international standard millivolt, resistance value corresponding to the display.
S percentage can display voltage and current measurements.
S thermocouple measurement, output, with functions of automatic or manual compensation.
S the output value of input in many ways.
S thermal bible resistance value and temperature value, can be realized fast peer review of millivolt values and temperature.
S built-in high-capacity rechargeable battery, a charge can work continuously for 5 ~ 7 hours () associated with the working conditions.
S big LCD backlit display, Chinese menu operation.
S key sound and backlight can be controlled, and can only every time on the last time the last setting condition.

Fourth, matters needing attention
Low, the output of the test and terminal connection must be consistent with the operation.For example, in the output terminal connected to measure the voltage, measure the voltage on the current terminal, may damage the instrument.
Confirm each range range, cannot be used in range.
Instrument in the sufficient light intensity, do not use a backlight, this can extend battery life.
Low when the instrument from the indoor scene and adopts automatic temperature compensation method, temperature difference is bigger, should adapt to 5 minutes at the scene, the meter instrument in the temperature of the temperature sensor and ring
Environment temperature is consistent, so as to accurately measure the environmental temperature.
Low output thermocouple signals, set temperature should be greater than or equal to compensate for temperature, make the output of the millivolt signal is positive.
