not be used on electrical equipment where voltages are present as the sensor is con-
nected to the stainless steel sheath. The following probes are isolated and suitable for
use on certain electrical equipment: TFT series, RET-1, ESO-1, IT-14, IT-18, IT-21.
Check with out technical department for details.
7.0 TROUBLE SHOOTING
a. Check that the instrument is switched on
b. Replace or recharge batteries
c. Excessive loading on the analog output. Remove the output plug
d. Probe or sensor may be faulty (open circuit). Check by substituting anoth-
er probe or by a resistance check. All probes should read less than 2000
ohms.) If you do not have a second sensor, bend a paper clip or other suitable
wire into a ‘U’ and insert into the socket instead of the probe. The instrument
should read room temperature.
e. Probe temperature is too high
f. Review measurement technique (Section 6.0)
g. Probe temperature below -100°C
