Test and calibration
Enter the hidden service menu to check the calibration
Enter Setup by long pressing Setup
key
Select “About” with arrow keys and
short press setup key, then leave
setup by long pressing setup key.
You should see the About screen,
Now press ALL the keys one after the other starting with the power key.

STEP 1, Low level transient
Connect the (x1) probe to the
scope probe test output,
If necessary adjust CV1 until pass
is displayed
See trimmer location
TRIMMER LOCATION,
If difficult to reach, gently re-
move the metal shielding.
Press RIGHTARROW KEY(*), now you should see the first calibration screen:
TIP: Pressing Right or Left arrow key, scrolls through
the calibration screens

Press RIGHT ARROW KEY,
STEP 2, High level transient
Connect the (x1) probe to the
scope probe test output,
If necessary adjust CV2 until
pass is displayed
See trimmer location
Press RIGHT ARROW KEY,
STEP 3, AD/DC Test
Signal should jump up and
down.
No adjustment, if fail, check cir-
cuit around relay RY1
Press RIGHT ARROW KEY,
STEP 4, 1V/div calibration
Connect the (x1) probe with a
3.4Vdc supply
If necessary adjust RV2 until
pass is displayed
Press RIGHT ARROW KEY,
STEP 5, 0.2V/div calibration
Connect the (x1) probe with a
0.7Vdc supply
If necessary adjust RV1 until
pass is displayed

Press RIGHT ARROW KEY,
STEP 6, 0.5V/div test
Connect the (x1) probe with a
0.7Vdc supply
No adjustment, if fail, check cir-
cuit round IC1, IC9, IC10
Press RIGHT ARROW KEY,
STEP 7, 0.1V/div test
Connect the (x1) probe with a
0.17Vdc (170mV) supply
No adjustment, if fail, check cir-
cuit round IC1, IC9, IC10
Press RIGHT ARROW KEY,
STEP 8, 50mV/div test
Connect the (x1) probe with a
0.17Vdc (170mV) supply
No adjustment, if fail, check cir-
cuit round IC1, IC9, IC10
Press RIGHT ARROW KEY,
STEP 9, 2V/div test
Connect the (x1) probe with a

Press RIGHT ARROW KEY,
STEP 10, Input transient
Probe section
Connect the (x10) probe at
scope probe test output.
Adjust the probe calibration until
pass is indicated.
Press RIGHT ARROW KEY,
STEP 11, Input transient
Scope section
Connect the (x10) probe at
scope probe test output
Adjust CV3 until pass is indi-
cated
Press RIGHT ARROW KEY,
STEP 12, Calibration END
If all steps where correct “Pass”
should be indicated, but due to
possible manipulation Fail,
could be indicated even if all
tests where OK.
