To change the display clear method
1. Press the menu keys.
2. Press the next key 6 times or until the “Auto
Reset” icon shows.
3. Press the save key to select the Auto Reset
function.
4. Press the next key until:
“AUt0” shows (Auto sense)
“Off” (manual clear using the clear key)
“1…….9” (seconds before the display clears
itself)
5. Press the save key to store new setting.
Note:
If auto sense is selected the torque meter will
automatically clear the display when a new
torque cycle begins. This means that you do not
have to continually reach up and clear the display
manually.
Entering the limits (tolerance) settings.
1. From the operation mode press and hold the
limits on/off key.
If you have set the % function set then the meter
will prompt you to enter the target tolerance (it will
automatically calculate the limits).
If you have the high/low function set then the
meter will first prompt you to enter the low limit
and then the high limit.
Power saving standby mode
When the torque meter has not been used for
approximately 3 minutes it will go into the power
down or “standby” mode. The display will show
“. . .”.
Press the clear key to get back to normal
operation. For the longest life from the batteries
turn the meter off when not used.
Entering Numbers
When a number needs to be entered or changed a
default value (or the last value entered) will be
shown.
The active digit that can be changed will blink.
Press the increase key to increase the value of the
blinking digit.
Press the next key to go to the next digit.
Press the increase key to increase the value of the
blinking digit.
Repeat for digits 3 and 4.
When the number is correct, press the save key to
save the new value.
Zeroing the display
If you press the increase and next keys at the same
time you will “Zero” the unit. Make sure that there
is no load on the transducer when pressing the zero
keys. The meter will not read torque until
approximately 2% of the transducer range has been
reached, therefore you should zero the unit even
when the display shows zero when changing
directions. The meter also does an automatic zero
when the power is turned on.
IMPORTANT!
Always zero the unit when changing direction. If you plan to use the meter in the
counterclockwise direction load the transducer three times in the counterclockwise
direction (to full scale) and then zero the display. Press the zero keys even if the display
shows “000.0” This will compensate for small amounts of hysteresis (hysteresis is a natural
characteristic of steel).
