NOTE
Throughout the entire procedure, TI averaging (MATH
function) may be used for a more stable indication.
a. Performance Check
NOTE
The ADC verification ensures that there are no significant
differences in the readings when changing resolutions and
measurement speeds with a constant input.
(1) Connect calibrator OUTPUT HI/LO to TI INPUT HI/LO.
(2) Press TI keys as listed in (a) through (i) below.
(a)
CLEAR
(b)
[PWR UP DFLT]
(c)
DCV
(d)
CONFIG
(e)
[FAST] (FAST de-selected)
(f)
[FILT] (FILT de-selected)
(g)
[RESL] , [7]
(h)
DCV
(i)
[20 V]
(3) Set calibrator to 0.0 VDC, output to OPR.
(4) Record TI displayed value in the reference column for this voltage level (first 4
(5) Using TI CONFIG menu, set RESL and FAST to the settings in the next row of
(6) TI will not deviate from the reference by more than the limits in table 3. If TI
exceeds the limits in table 3, perform b below.
(7) Repeat technique of (5) and (6) above for remaining TI RESL and FAST settings
at this voltage level with this reference. TI will indicate within the limits of table 3.
(8) Set calibrator to +10 V dc, output to OPR.
(9) Using TI CONFIG menu, set RESL to 7 and ensure that FAST is de-activated
(reference settings for +10 V dc input).
(10) Repeat technique of (4) through (7) above for remaining TI RESL and FAST
settings in table 3 at +10 V dc. TI will indicate within the limits of table 3.
(11) Set calibrator to -10 V dc, output to OPR.
(12) Using TI CONFIG menu, set RESL to 7 and ensure that FAST is de-activated
(reference settings for -10 V dc input).
(13) Repeat technique of (4) through (7) above for remaining TI RESL and FAST
settings in table 3 at -10 V dc. TI will indicate within the limits of table 3.
