Current 

Ramping 

tests 

(Peak 

Amps,  Build  Time,  Drive 

Time),  Ignition  KV,  and  Differential 
RPM. 

Build time is the time it takes the current 
driven  into  an  injector  or  ignition  coil 
to  reach  its  peak  value.  Build  is  the 
equivalent to Dwell on a current limited 
ignition.  The  upper  display  shows  the 
peak  current  that  the  coil  was  driven 
to.  Drive time is the entire time that the 
injector  is  driven  open  or  the  ignition 
coil is driven prior to firing. Drive time 
is  the  equivalent  to  Dwell  on  a  points 
and ballast type ignition system. 

An  optional  adapter  is  needed  to 
use  the  KV  test.  The  adapter  KV  clip 
is  attached  to  a  spark  plug  wire  and 
the  magnitude  of  the  KV  peaks  are 
displayed  on  the  lower  display.  The 
BARGRAPH indicates activity of the KV input between numerical 
updates.  See the expanded section on KV to learn more

When using the Differential RPM test, RPM is shown on the upper 
display and the lower display is normally blank. Pressing REL0 
sets and reference RPM value. While the REL0 mode is indicated 
the difference from the reference RPM is displayed on the lower 
display. A negative number means that the current RPM is lower 
than the reference RPM by that amount. A non-negative number 
means that the current RPM is higher than the reference RPM. 
Pressing REL0 will exit the mode and clear the lower display.
