4.3 Calibration
To ensure the accuracy of the Meter, Scheduled
calibration is recommended and should be performed
only by qualified personnel. Calibrate the Meter
annually is recommend. Calibration frequency can
be higher or lower to every three years depend of the
frequency of the usage.
• Accuracy (perform under temperature of 25°C):

Humidity Sample Speed:240ms ; LCD refresh time 3.5s
• Operation Temperature: -10~50°C(14~122°F)
• Storage Temperature: -40~60°C
(
-40…140°F)
4 Maintenance and Repair
4.1 Repair
Please follow the steps closely if the Meter is not
functioning properly:
1. Check the batteries, replace new batteries if low
battery indicator “ ”appears.
2. Follow Users Manual to confirm every procedure.
3. Before sending back the Meter for repair, include
a description of the problems encountered. Remove
the batteries and pack the Meter well to avoid
possible damage by the delivery, Mastech does
not cover the damage due to delivery.
4. Repairs or servicing not covered in this manual
should be performed only by the authorized service
center or qualified personnel.

2.3 Measure/Hold
•
•
To hold the readings, press “Hold” button till the Hold is
displayed on the top right corner.
To cancel hold of the readings, press “Hold” button
again till the Hold indicator disappear, the Meter will
now show current readings.
2.4 Maximum/Minimum
•
•
•
•
To show the maximum of the moisture readings,
press “MAX/MIN” button till “MAX” is displayed.
To show the minimum of the moisture readings, press
“MAX/MIN” button till “MIN” is displayed.
To show current moisture readings, press “MAX/MIN”
button till the LCD does not display “MAX” nor “MIN”
In “MAX” or “MIN” mode, if the “MAX/MIN” button is
not pressed for 5 minutes, the Meter will switch back
to current moisture readings.
2.5 Switch between Functions
•

“°F”,
Press “Unit” button to switch between functions
“
”,
“%”, “WB” and“TD” (Symbols flash).
Press “Enter” button to confirm selection. If no
selection is confirmed in 8 seconds, the Meter will
exit switching mode.
2.6 Backlight Display
•
Press the backlight button ( ) to turn on the
backlight, press again to turn it off. The backlight
