In above step A of CURRENT MEAS. ACCURACY CALI., the display shows the offset of Iac
and Idc measured by AC source. They are produced by internal components. Wait a few
seconds then press
ENTER
, then Iac = 0.00A, Idc = 0.00A.
Then press
SHIFT
, then to change to next step.
In above step B of CURRENT MEAS. ACCURACY CALI., press
ENTER
then AC source will
output 12.5VAC. The user should apply suitable load to output, to make the output current
measured by current meter (or power analyzer) be about 1.6A (for 61504). The different
model shows different current value in display. If the output current is ok after applying load,
press
ENTER
, then AC source will output 125VAC. The output current will be 10 times of
step B, 16A. Keyin the exact value of current measured by current meter. The output
current of step B. and step C. are shown as below:
Model Step B. Step C.
61501 (500 VA) 0.4 A 4 A
61502 (1000 VA) 0.8 A 8 A
61503 (1500 VA) 1.2 A 12 A
61504 (2000 VA) 1.6 A 16 A
Step C is the final step of CURRENT MEAS. ACCURACY CALI. Press
PAGE/EXIT
to exit
that page. Then display will show as below. Press
ENTER
to save the calibration result.
Press ( ENTER ) to save .
