Operation 

 
 
 
 
 

1. 

Remove the protective cap to expose the electrode pins. 

2. 

The meter automatically switches ON when the cap is removed. 

3. 

The meter automatically shuts OFF when the cap is replaced. 

4. 

To conserve battery life, the meter automatically shuts off after 15 minutes when the cap is 
left off. To revive the meter after an Auto Power OFF, simply press the yellow cut-off switch 
momentarily. 

5. 

Slide material selection switch to read wood moisture or building moisture. 

6. 

Carefully push the electrode pins as far as possible into the material under test. Note that 
the pins should be inserted into wood perpendicular to the wood’s fiber structure. 

7. 

Take several readings in several locations on the material for the best representation of the 
amount of moisture present. 

8. 

Read the measurement values on the display. 

9. 

Replace the protective cap when finished. 

Reading the Display 

1. 

The LCD display has two scales  

2. 

The wood scale indicates wood moisture from 6 to 44%.  

3. 

The building materials scale indicates moisture content 
from 0.2 to 2.4%.  To calculate the Wood % equivalent 
multiple the building material reading by 20.  
(example – 0.6% building x 20 = 12 %WME).  

4. 

A continuous line indicates an even number. A dotted line 
indicates on odd number. 

5. 

The battery icon appears when the batteries are weak and 
require replacement. 

 

Auto Power OFF 

With the protective cap removed, the meter will turn off after 15 
minutes to conserve battery life. Press the yellow cutoff switch 
momentarily to restart the meter. Always secure the protective 
cap when the instrument is not in use. 

Instrument Measurement Verification check 

1. 

With the meter wood moisture position, touch the electrode test pins to the two test points 1 
and 2 at the top of the protective cap labeled ‘T’. 

2. 

With the unit on and the electrode pins touching the ‘T’ test points, the meter should read 
27% ±2%. If not, the meter may require repair. 

Battery Check 

1. 

With the meter wood moisture position, touch the electrode test pins 
to the two test points 3 and 4 at the top of the protective cap labeled 
‘B’ (see diagram). 

2. 

With the unit on and the electrode pins touching the ‘B’ test points, the meter should read > 
44%±2% on the wood moisture scale. If not, replace the batteries. 

CAUTION

: The electrode measurement pins are extremely sharp. Use 

care when handling this instrument. Cover the pins with the protective cap 
when the instrument is not in use.
