4.1 Troubleshooting
Problem Possible Cause Solution
Display is blank when POWER
key is pressed
Discharged battery Replace cells, or if using NiMH, recharge
Defective battery Replace
Corroded battery or battery contacts Clean contacts
Defective switch or circuit board Requires authorized service
Display does not function
properly or front panel keys do
not function normally or
Dyna-Clamp not powering off
Improperly loaded software Reinstall software
Faulty circuit board Requires authorized service
Loose connectors Requires authorized service
Dyna-Clamp does not respond
to tension changes
Out of calibration Requires authorized service
Faulty load cell Requires authorized service
Worn out or damaged drive rod Requires authorized service
Display over ranges below 100%
of capacity
Zero requires adjustment Rezero the Dyna-Clamp
Too much tension/load has been zeroed Rezero the Dyna-Clamp
Display drifts AZM (Auto0) is turned off Turn AZM on
Rapid temperature changes such as moving
the Dyna-Clamp from indoors to outdoors
Wait until the Dyna-Clamp temperature has stabilized
Displayed tension shows larger
error
Dyna-Clamp not zeroed before load is lifted Zero the Dyna-Clamp with no load attached
lbf/kgf/kN units causing confusion
Select proper units
Requires recalibration Requires authorized service
Display reading not stable Excessive vibration in wire rope Increase filtering
Load cell faulty Check LC connections
Display toggles between Error
and Load
Tension exceeds capacity Immediately reduce tension
Faulty load cell or wiring Check LC and LC wiring
Display toggles between Error
and Key
A key is stuck or is being held down Check switches for damage
Ensure that a remote is not continuously transmitting
Low battery is blinking Battery is low Replace (alkaline) or recharge batteries
Unit turns on then immediately off Battery is low Replace (alkaline) or recharge batteries
Tension does not zero System not stable Wait for standstill annunciator to turn on
Increase filtering for more stability
Zero out of range Zero range might be limited; only zero while Dyna-Clamp is not
clamped to a wire rope
Tension does not average System is not stable Wait for standstill annunciator to turn on, or see Display reading not
stable above for an additional solution
Low threshold % of capacity not met between
average measurements
Remove Dyna-Clamp from the rope being tested, the device must drop
below the low % of capacity before a new average can be taken
Setpoint LEDs blink Range is enabled and a trigger point has
been reached
Disable range if it is not needed
