Product Characteristics
● Insulation between channels
● Multi-channel data recorder with universal signal input that can be used independently
●
Support all types applied flexible signal input system
● Support remote monitoring and wireless LAN function for data logging
● 32G SD card storage capacity
● Support 5ms interval sampling at maximum
● Thermocouple measurement accuracy increased by 50%
● Resolution sample signal up to 1µV
● 5.6 inches (640x480 dots) TFT LCD display with a wider viewing angle
■ Output mode: collecting electrode open circuit output (upper resistance 10kΩ) <maximum output of triode>
Voltage: 20V, · Current: 0.1A, r · Collector dissipation: 0.2W
■ The minimum sampling interval varies with the number of channels used.
■ Each channel can independently specify the output port.
■ When using the WLAN module, the SD memory card socket cannot be used.
■ The maximum number of recorded data is 4/5 of the available storage space.
■ The screen display is switched by pressing the key. In the enlarged numerical display screen, the channel
number can be specified. In the waveform display mode, the change of the time scale is effective from the next point.
■ The power consumption is in the state of using the AC adapter, LCD display, and dry battery charging.
■ Terminal "b" for thermal resistance, all channels are connected together.
■ Satisfy following conditions:
23℃±5℃
More than 30 minutes after turning on the power
filter ON(10)
Sampling speed：1s(JK350:10ch)
GND
■ The thermocouple used is T/K type 0.32φ,Other as when using 0.65φ.
