Tips: Troubleshooting & maintenance of C703 handheld signal source calibrator

1. Troubleshooting

Nothing displays on the LCD screen after turning on the signal source.
a. Check if the battery is OK.
b. Check if the power adapter outputs the current of 1000mA.
The measurement result cannot display.
Make sure that the signal source calibrator is on the status of MEASURE.
The output or measure value is abnormal.
a. Check if the signal wires are connected correctly.
b. Make sure that the right signal type is chosen.

2. Maintenance

This handheld signal source calibrator is powered by 3.7V rechargeable lithium battery. For a long time use, please power it by power adapter so as to extend the lifespan of battery.
If you use a phone charger to charge the instrument, please confirm that the phone charger output current is 1000mA.
The instrument is not waterproof. Please keep it away from too humid environment.

How to Differentiate Between Active & Passive Signals
The handheld voltage current thermocouple calibrator is a portable measuring device mainly used to calibrate thermocouple sensors. A thermocouple sensor is a common temperature measurement device that measures temperature based on the temperature difference at the point of contact between two different metal materials. The handheld voltage and current thermocouple calibrator provides accurate voltage and current outputs for simulating different temperature environments to calibrate thermocouple sensors. The following will show you directly through the basic experiment of distinguishing active signals and passive signals, using a handheld precision multifunction calibrator, a multimeter and a DC power supply to build a signal acquisition loop.

Existing reviews of Handheld Voltage Current Thermocouple Calibrator, Output Signal Source

Great signal source

This handheld signal generator is right for me. It is small and easy to carry. Just put it in my pocket when I go to the industrial site. Besides, it is not too complex and I can operate this very well soon. Works as advertised.
