Calibrating the HM40 Using HMK15

The HMK15 Humidity calibrator allows you to produce
known humidity environments using saturated salt
solutions.

Performing a good calibration takes some time and
preparation. Read the HMK15 User’s Guide before
performing your first calibration with the HMK15.

1.

Press the Menu button and select

the Calibration submenu.

2.

Select the parameter to be

calibrated at menu item [1]
Quantity. You can calibrate
Temperature (T) or Relative
Humidity (RH) measurement. All
other humidity parameters are
calculated from RH and T, so they
will also be adjusted.
