A calibration is recommended. TORKEL is now using
calculated and standardised calibration values.
“Checksum error! Switch off”
Read error in TORKEL's control-memory.
Switch off TORKEL and switch on
again. If the message remains it
might be necessary to perform
the reset procedure in the chapter
“Calibration”.
•
“Power failure”
TORKEL has lost the mains power for a while when a
test was in progress. TORKEL displays the values when
the test was interrupted.
You can choose to continue or end
the test.
•
"8X0"
You need to restore Torkel, follow instructions below.
Connect Torkel to the PC and start
Torkel. Press "ESC" to enter the main
menu.
Run the file "restore.exe" and select
the file xxxxxxx.set (contact our
Customer Service if you do not have
the file).
Click the icon "TORKEL Restore" and
select the "Com port".
When the message "Restoring com-
plete" is shown, click "OK".
Calibrate Torkel.

Check the setting in sub menu “Basic
setting”, “I measurement”.
Select “
External
” if you want to use
the input External Current Measure-
ment.
Select “
Internal
” if you do not want to
use External Current Measurement
Check that the mV/A ratio complies
with the clamp-on ammeter

TORKEL is set for “External Current Measurement” but
the clamp-on ammeter:
is not properly connected
is not switched on
is not correctly applied on the
conductor.

•
•
“Overheated”
The internal thermal protection device has tripped.
Check cooling and ambient tem-
perature
•
A fan may be damaged (not rotating or slow).
Call for service.
•
“Overcurrent”
The current through TORKEL is higher than allowed
because of a fault in TORKEL´s internal current limita-
tion.
“Input voltage too high”.
The battery voltage is higher than specified for your
TORKEL.
“Input voltage > 27.6 V”
“Input voltage > 55.2 V”
“Input voltage > 144 V”
“Input voltage > 288 V”
“Input voltage > 480 V”
When you connect the battery, TORKEL will automati-
cally select the voltage range and arrange the internal
resistors for highest possible current.
If one of the messages above appears, TORKEL has
stopped because the input voltage has increased and
exceeded the range. You can continue the test but
TORKEL will choose a higher voltage range and rear-
range the internal resistors.
Note: The current rating for the new range is prob-
ably lower than the previous range (see chapter
headed “Specifications”).
“Input voltage too low”
The battery voltage is too low (less than 10 V, which
is frequent on defective batteries) for safe operation
with TORKEL.
