Checking Calibration

Calibration is factory set. It may be checked by using a

Wagner Calibration Verification Block (CVB) (P/N: 840-

60130-002). Use only to verify L610 factory calibration is

within tolerance limits. If calibration is out of tolerance,

return L610 to factory or repair depot for re-calibration.

Never adjust L610 to this device. Protect CVB from

direct sunlight. Store in cool dry place. Follow these

steps for checking calibration.

1. Enter the Calibration menu item.

2. Hold the meter in mid air so the bottom is several feet

from any object. The correct reading for air is .0

%MC. If the reading is outside the range, -2 to 2

%MC, the unit is out of calibration.

3. Place the CVB, rubber feet down, on a metal surface:

such as a file cabinet, a piece of sheet metal, etc.

4. Orientate the long axis of the handmeter with the long

axis of the CVB. Press the handmeter sensor in the

center of the CVB and observe the reading. The

correct reading is 17.5 %MC. If the reading is outside

the range, 15.5 to 19.5 %MC, the unit is out of

calibration.

Warning—There are two (2) hole plugs located on either

side of the L610 handle. Do not remove these plugs

because the adjustments below them are factory set and

should not be adjusted by the customer. If adjustment is

attempted, the unit will not be in calibration and will

require factory re-calibration. Also if adjustment is

attempted, warranty will be voided.
