Operation
Preparation
1. Before starting a test, close all valves and ensure that all regulators are
rotated fully counterclockwise.
2. Connect the heating well to a 110V or 220V AC power source as specied
on the nameplate. The heating jacket requires an 800W power supply.
3. Turn the thermostat to about mid-scale to begin heating and place a metal
dial thermometer in the thermometer well.
The pilot light will turn on when the heating well is at the temperature
setpoint. The temperature should read 10°F (6°C) above the desired test
temperature. If it is not, adjust the thermostat.
4. Before using the ceramic disk, soak it for at least 10 minutes in base uid.
Use water for freshwater-based uids, brine for saltwater-based uids,
diesel for oil-based uids, and a synthetic base for synthetic-based uids.
Never reuse a disk except for return permeability studies. Below is a list
