If this unit does not work properly, please take the following measures. If the trouble stillcannot be solved, then please contact our company.
At query, please inform us the model name, product serial number, and conditions of thisunit as detailed as possible. The model name of Load Cell or sensor connected to this unit
should be also informed.
７－１) Basic check point
1) . Please check if using a correct power supply.
this unit is supplied voltage with AC85～132V as standard or DC20～27V as option.
2) . Please check that wires are connected to the terminal base correctly and firmly.
７－２) Precautions at the time of calibration
1) ． Error occurs at the time of zero point calibration.
・In case of exceeding the setting range of zero point.
To perform zero point calibration, Load Cell output with no load should be in the rangeof -2.8～+2.8mV/V
2) ． Error occurs at the time of span calibration, or display value is not correct as set in spancalibration. Or minimum scale is not correct as set in Function Mode.
・This unit cannot measure in a system that the sum of initial tare value and measured
value exceed 3.3mV/V.
・In case resolution cannot be achieved at the minimum scale which set at Function Mode,the minimum scale will automatically be changed in order to achieve the resolution.
Since the input sensitivity of this unit is 1μV/digit, the maximum display resolution is
1/5,000 when input 1.0mV/V, and it is 1/2,000 at the time of 0.4mV/V. Resolution of
exceeding these values cannot be set.
７－３) Countermeasures for unusual display
1) ． The measured value is blinking (over load indication) when not overloaded
A part of sensor cable might be broken or a sensor itself might be defective.
Please confirm the input voltage (mV/V) from a sensor in Test Mode.
７－４) Judgement whether this unit has malfunction1). Please confirm whether a sensor excitation voltage is correct. Disconnect a sensor fromthis unit and check the voltage by a tester between #1(+EXC) and #2(-EXC) of terminal
block. Please check whether it is stable at 5V ± 0.25V(EXC=5V) or 2.5V ± 0.13V(EXC=2.5V)
If it is unstable, power circuit for a sensor in this unit is failure.
2) . Short-circuit (Jumper between No.3 (+SIG)～No.4 (-SIG)) of the output voltage of asensor at terminal block and display input voltage (mV/V) in Test Mode. Then pleasecheck if the input voltage is stable nearest to zero.
If unstable, this unit is failure.
If stable, please check a sensor side.
3) . Checking a Relay contact output
