The multi-function signal calibrator is a portable full-function calibrator designed for the conveni…

Products overview:
ZW - YF - 518 series multifunctional signal checking instrument not only can measure the voltage, the millivolt signal, can also be allocated to the eight kinds of thermocouple (J, K, T, E, B, R, S, L, N) and six kinds of thermal resistance (PT100, PT200 PT500 PT1000 Cu50 PTJIS) measure temperature;Can output voltage signals, millivolt, resistance, and simulate the thermal resistance and thermocouple output, but also can provide DC24V power distribution.For full digital operation, the large lattice LCD screen, can online charging, applies to the laboratory, and convenient to use at the scene.
Second, the applications.
ZW - YF - 518 seriesMultifunctional signal verificationisDesigned for the convenience of laboratory calibration fully functional portable checking instrument, and has a wider scope of work and calibration.All process parameters can be measured and output, suitable for all kinds of calibration purposes.V, mV, mA, Ω and thermocouple (TC), thermal resistance (RTD) signal output and measurement.24 v DC power output for transmitter loop power supply, and can simultaneously measure the transmitter output by mA value.

Three, the main features:
1, portable general case, easy to carry, easy to operate.Metal shell, good durability, strength, strong anti-interference ability;
2, 5 1/2 a LED display, zui xiaoke distinguish the slight variation in pressure of 1 pa;
3, equipped with DC24V constant-voltage source output and loop current measurement function, meets customer application conditions;
4, accurate comprehensive zero, linear and temperature drift compensation, ensure that the instrument with high accuracy within the specified conditions of use;
5, aluminum alloy boxes, ensure instrument transport and carry from harm;
6, built-in high-energy lithium (nimh) batteries, instrument in the field without mains sites can work continuously for more than 10 hours;
7, under-voltage and overcharge protection circuit and Settings, greatly improving the service life of the battery.

Four, the technical parameters:
1 no potentiometer, numeric keys to set the whole process, operation, complete function;
2, measure the fixed value output, continuous lose;
3, resistance and Pt100, Pt1000, Cu50, Cu100 uniform degree of the output of the thermal resistance and measurement;
4, E, J, K, T, S, B, R, N and the output of the thermocouple and measurement and cold junction compensation, temperature display, do not need to look up table;
5, process the measurement and simulation of signal mV, V, mA;
6, frequency (HZ) measurement and simulation;
7, buttons simulated coarse, medium and fine adjustment, direction, continuous output, with step by step, slope, maintain, and other functions;
8, DC24V dc voltage source;
9, prepared by RS232 interface, through the PC to realize the remote control and instrumentation out-of-tolerance timely correction;
10, appearance size: 290 * 250 * 105;
11, weight: 1.5 kg.
Five, the use matters needing attention:
Instrument should be placed in a clean, no corrosion environment, if you have special request, please indicate in the contract.
Cannot use chemical solvents such as gasoline, alcohol scrubbing panel.
Don't let the soldering iron and other heating element near the screen, this will prevent the burnt plastic resin materials.
Instrument has enough ability to overload, but do not serious overload, otherwise will cause the damage of the sensor, instrument cannot be used.
Instrument is a seismic design, but still should be carefully handled very much, especially when used at the scene, avoid the fall, a collision.
Instrument sensors are high precision products, silicon diaphragm don't collide with the solid surface, otherwise it will damage the sensor.
No professional testing skills and dedicated testing equipment, do not open the machine cover for maintenance, are not allowed to adjust the internal components and replacement material, otherwise there is no guarantee that the reliability of the instrument.
Instrument need not when, should turn off the power supply, long-term need not when, charge once three months.
Portable pressure check light with light, should be paid attention to avoid strong vibration stress check and avoid in corrosive gases or surrounding the humidity is very big, high temperature heat sources.

Six, output indicators:

Seven, thermal resistance measurement and accuracy of output:

Measurements:

Nine, thermocouple measurement and accuracy of the output:

Quality assurance and after-sales service: 
ZW - XY518 seriesMultifunctional signal verificationProduct quality assurance period for 12 months, lifelong maintenance.Warranty period for the damage, free maintenance, more than warranty, maintenance fee and shipping fee only.To new users first use, generally by the menu function prompts the operation, there are technical difficulties, please call the company technical department to give answers.Company can send engineers to the scene guidance when necessary.
