Operating Manual
voltage to zero within ±100mVDC, the LED will display "FAIL". And you can press the ENTER key
(in the middle of the five EDIT keys) again to start the Auto-Zero process. And you can select
function to monitoring state and change the setting to DC and then press the ENTER key (in the
middle of the five EDIT keys) to view the DC output voltage on the LED display.
The output of the amplifier needs to be within a range of ±0.1VDC or ±10VDC/gain, whichever is
greater, for the Auto-Zero to function. The resulting zero trim correction value is stored in non-
volatile memory until overwritten in any subsequent Auto-Zero operation. Turning "OFF" Auto-
Zero returns to an un-adjusted output state.
Set Shunt Calibration
Depress the "Select Function" push-button to select the "Shunt Calibration" for programming, and
then the corresponding "Function LED" will illuminate and stay illuminated until the "Select
Function" push-button is pressed again to select the next function.
This function selection provides for connecting the external or internal shunt calibration resistors
installed with several modes.
The left-right EDIT keys select the number position in the LED display, and then the selected
number position will be blinking to indicate the number selected for programming. And the up-
down EDIT keys can modify the selected number. The five characters about the LED display will
be divided up to two parts, and the blinking position can be moved alternately in this two parts
each time the left-right EDIT keys are pressed.
And the following messages will be shown alternately on the LED display each time the up-down
EDIT keys are pressed:
On the left of the two parts, there will be shown alternately as "EL", "S+" or "S-". And on the other
side of the two parts, there will be shown as "OFF", "P+" or "P-" alternately.
The setting will be active only after the ENTER key (in the middle of the five EDIT keys) is
pressed.
Set Monitoring State
Depress the "Select Function" push-button to select the "Monitoring State" for programming, and
then the corresponding "Function LED" will illuminate and stay illuminated until the "Select
Function" push-button is pressed again to select the next function.
The left-right EDIT keys select the number position in the LED display, and then the selected
number position will be blinking to indicate the number selected for programming.
There will be display as "AC", "DC" or "OFF" alternately on the LED display with depress the up-
down EDIT keys each time.
The setting will be active only after the ENTER key (in the middle of the five EDIT keys) is
pressed, and then LED display will show the RMS AC voltage output, DC voltage output or
disable the monitoring function accordingly.
