Function Check for RH measurements: Step 1
Accuracy check for RH BluePeg probe: Step 2
Step 1: Connect the RH BluePeg probe to the
Ligno-VersaTec using the small RH adapter and
also the RH cable. Press the READ key. A value
for either RH, T, DT or GPP appears. Press the
HOLD key and then the up key repeatedly to
recall the other values. Check if the indicated
values are within the expected range. If you read
a temperature of 150
0
F, you know something is
wrong. We recommend this test before using the
RH BluePeg probes for the first time.
Step 2: The accuracy of the RH BluePeg probe needs to be checked periodically. This
check can only be performed by exposing the sensor on the circuitboard to a known
relative humdity. For on-site checking we sell salt solutions for 75% and for 33% RH.
Accuracy check for in-situ RH probes for concrete moisture testing: The ASTM standard
F2170 sets the rules for test equipment, procedure and frequency of accuracy testing.
Since the standard is still modified periodically, we recommend to purchase the latest
F2170 standard to be up-to-date with all requirements. Available from the ASTM web-
site. Lignomat offers to check RH probes three times free of charge during the first year.
