Using a check handle

A check handle is used to confirm that LT operates properly.
• Use the check handle to verify the operation after the tank has been filled with
liquid.
• The check handle is not a float hoist handle. Do not forcibly hoist the float using the
check handle.
• For using a hoist handle, see →  76
Procedure for using the check handle
1. The check handle is located at the bottom of LT' s main body. Push the check handle
into the LT.
2. Return it to the left side when it points to 4 to 5 mm (0.16 to 0.20) above the
indicator on the scale plate, and let go of the check handle.
3. Check the indicator on the LT' s scale plate.
This completes the procedure for using the check handle.

Using a hoist handle

7.2.1 Hoist handle (for LT5-1)
A hoist handle is used to hoist up the float when it is not being used to measure the liquid
level. This helps to add life to LT when utilized for tanks with a stirrer and/or for tanks
containing corrosive liquid.
• Never let go of the handle when hoisting or lowering the float. Letting go of the
hoist handle may cause the float to fall and damage LT.
• Stop turning the handle once the float has reached the liquid level after being
lowered down.
• When the hoist handle reaches position A in the following diagram, the float will be
freed from the handle. Remove the handle while the float is in use.
