slowly varying temperature. Large temperature
variations from cycling air conditioning or forced
air heating will degrade performance.
• Intermittently run the 0.5 KCl in continuous
mode between samples. Adjust your sample
readings up or down according to the amount of
variation from the 0.5 molal KCl.
• If using a WP4-T, set the block temperature to
best match the temperature of your samples.
This will help reduce error resulting from
changes in ambient temperature.
