DISPLAY PERFORM/RESULT a. b. c. d. e. Pull VTM switch to OFF. Remove  current  probe  from  positive  bat- tery  cable. Connect  current  probe  to  cable  connecting series  pair  of  batteries  together. Push VTM switch to ON. Select TEST 73. NOTE Both   TEST   73   and   TEST   75   must   be performed  to  determine  condition  of  se- ries  pair  of  batteries. 2. Perform offset test. a. Press and hold TEST button until CAL appears.  Release  TEST  button. b. If VTM reads between -225 and +225, offset  test  passes. c. If offset test fails, see TM 9-4910-571-12&P. 3. Press and release TEST button. 4. When GO appears, crank engine for two seconds  or  until  one  of  the  following  appears on  display: a. OFF b.  A  number Stop  cranking  and wait  for  message  to appear. BATTERY RESISTANCE (milliohms  test  73; milliohms/seconds test 75) c.  .9.9.9.9 Beyond   range   of VTM,  cannot  be measured. d.  Error  message See  page  3-242 e.  (-  -  -  -) VTM  lost  power during  test. Batteries  may  be too  weak.  Try powering  VTM using   external source. 5.  Observe  VTM  reading. a. If test 73 VTM reading is 25 or less, test passes. b. If test 73 VTM reading is over 25, test fails. c. If test 75 VTM reading is 50 or less, test passes. d. If test. 75 VTM reading is over 50, test fails. GO TO NEXT PAGE Change  4 3-291
