(4) Measured value span adjustment
Display MEASURED VALUE SPAN ADJUSTMENT referring to page 39 "7-5
PARAMETER SETTING 2". Then use the UP, DOWN and CHECK keys to adjust the
MEAS 2 display to 100% of the meter scale.
Finalize the adjustment by pressing the SET key.
Adjustable range is ±5% of monitor range.
(5) Recorder output zero adjustment
Display RECORDER OUTPUT ZERO ADJUSTMENT referring to page 32 "7-5
PARAMETER SETTING 2", and make the reference sine wave input voltage from the
function generator 0%. Then use the UP, DOWN and CHECK keys to adjust the recorder
output measured with the DMM to 0% of output value.
Finalize the adjustment by pressing the SET key.
Adjustable range is ±5% of monitor range.
• 0% output is 1V if the recorder output specifications is 1 to 5VDC, or 4mA if it is 4 to
20mADC.
• MEAS 2 indicates the measured value.
(6) Recorder output span adjustment
Display RECORDER OUTPUT SPAN ADJUSTMENT referring to page 39 "7-5
PARAMETER SETTING 2", and make the voltage input voltage from the synthesizer 100%.
Then use the UP, DOWN and CHECK keys to adjust the recorder output measured with the
DMM to 100% of output value.
Finalize the adjustment by pressing the SET key.
Adjustablet range is ±5% of monitor range.
• 100% output is 5V if the recorder output specifications is 1 to 5VDC, or 20mA if it is
4 to 20mADC.
• MEAS 2 indicates the measured value.
