Meter does not turn on:
1. Press
POWER
for more than 2 seconds.

Unstable readings:
1. Stir the solution to make a uniform sample and make sure the sensor is
completely immersed in the solution. The measurement must be done
while the probe is in the container/solution.
2. Clean and re-calibrate or replace the probe.
3. Move to a new location for measurement, RF emissions from unknown
sources may disrupt readings.
Readings not changing:
1. Check to see if the meter is in Hold Mode.
2. Release the “HOLD” function.
3. Check to see if the meter is in “MTC,” if so, input the temperature value.
Slow response:
1. Clean and re-calibrate or replace the probe.
Wrong real time:
Incorrect real time display will not affect the measurements. The
internal battery needs replacing. Contact Sper Scientific for battery
replacement procedures.
