- mV to mA Converter
G.M. International ISM0098-8
For D1010S-054
Set calibrator (CAL) at - 5.000 mV and verify that the output current, read by multimeter (DMM), is correspondent with a maximum deviation presented in the section “Technical Data”.
Set calibrator (CAL) at 55.000 mV and verify that the output current, read by multimeter (DMM), is correspondent with a maximum deviation presented in the section “Technical Data”.
If the maximum deviation is exceeded, repeat the board calibration and proceed in the following way:
Set the calibrator (CAL) at 55.000 mV and regulate the current, read by multimeter (DMM), by turning the span trimmer of the unit (see “Configuration” section) until reading
20.000 mA ± 5 µA value.
Set the calibrator (CAL) at - 5.000 mV and regulate the current, read by multimeter (DMM), by turning the zero trimmer of the unit (see “Configuration” section) until reading
4.000 mA ± 5 µA value.
Repeat the last two steps to verify that the span trimmer’ s movement has not significantly modified the value of zero (a dragging of 1/5 exists when moving span and zero values.
To execute a linearity test: set the calibrator (CAL) at - 5.000, 10.000, 25.000, 40.000, 55.000 mV and verify current output is correspondent at 4.000, 8.000, 12.000, 16.000,
20.000 mA with a maximum deviation presented in the section “Technical Data”.
For D1010S-056
Set calibrator (CAL) at - 5.000 mV and verify that the output current, read by multimeter (DMM), is correspondent with a maximum deviation presented in the section“Technical Data”.
Set calibrator (CAL) at 35.000 mV and verify that the output current, read by multimeter (DMM), is correspondent with a maximum deviation presented in the section “Technical Data”.
If the maximum deviation is exceeded, repeat the board calibration and proceed in the following way:
Set the calibrator (CAL) at 35.000 mV and regulate the current, read by multimeter (DMM), by turning the span trimmer of the unit (see “Configuration” section) until reading
20.000 mA ± 5 µA value.
Set the calibrator (CAL) at - 5.000 mV and regulate the current, read by multimeter (DMM), by turning the zero trimmer of the unit (see “Configuration” section) until reading
4.000 mA ± 5 µA value.
Repeat the last two steps to verify that the span trimmer’ s movement has not significantly modified the value of zero (a dragging of 1/5 exists when moving span and zero values.
To execute a linearity test: set the calibrator (CAL) at - 5.000, 5.000, 15.000, 25.000, 35.000 mV and verify current output is correspondent at 4.000, 8.000, 12.000, 16.000,
20.000 mA with a maximum deviation presented in the section “Technical Data”.
For D1010S-057
Set calibrator (CAL) at - 5.000 mV and verify that the output current, read by multimeter (DMM), is correspondent with a maximum deviation presented in the section “Technical Data”.
Set calibrator (CAL) at 10.000 mV and verify that the output current, read by multimeter (DMM), is correspondent with a maximum deviation presented in the section “Technical Data”.
If the maximum deviation is exceeded, repeat the board calibration and proceed in the following way:
Set the calibrator (CAL) at 10.000 mV and regulate the current, read by multimeter (DMM), by turning the span trimmer of the unit (see “Configuration” section) until reading

To execute a linearity test: set the calibrator (CAL) at - 5.000, - 1.250, 2.500, 6.250, 10.000 mV and verify current output is correspondent at 4.000, 8.000, 12.000, 16.000,
20.000 mA with a maximum deviation presented in the section “Technical Data”.
