This adjustment affects the transmitter s accuracy. Be sure to set the duty ratio within 0.% allowances. ) Confirm that the input monitor LED (PL) is ON (it should actually be flashing in khz). If the LED does not turn on, the detecting level may be out of the pulse amplitude range. Change the detecting level again. P. / EM- Rev.
JTY SENSOR EXCITATION ADJUSTMENT You can change the sensor excitation voltage with the sensor excitation adj. located behind the front cover. If you need to change it, check that the required current is within the specification. ALARM OUTPUT 0 OUTPUT INPUT SENSOR EXC.

Check that the current value indicated on the ammeter is within the allowable limit. If the value is greater than the limit, lower the voltage value or connect a separate power source. Otherwise, the transmitter may fail.

For matching the signal to a receiving instrument or in case of regular calibration, adjust the output as explained in the following. How to Calibrate The Output Signal Use a signal source and measuring instruments of sufficient accuracy level. Turn the power supply on and warm up for more than 0 minutes. ) ZERO: Apply 0% input and adjust output to 0%. ) SPAN: Apply 00% input and adjust output to 00%. ) Check ZERO adjustment again with 0% input. ) When ZERO value is changed, repeat the above procedure ) ).
