Make sure that the adapter inserts and probes are not contaminated with any substances (e.g. oil) that
may cause ignition or explosion during heating.
Attention
Never fill liquids into the adapter sleeve.
Danger of burn!
Before touching the block or the adapter insert, check the current block temperature since a heated
calibrator bears the imminent risk of burns.
Never remove adaptor inserts from a heated block since heated adapter inserts bear a fire hazard.
Never remove probes from a heated block since these bear the imminent risk of burns.
Never leave a heated calibrator unattended.
Always let a heated calibrator cool to below 50 °C before disconnecting it from the mains.
Transport the calibrator only after it has completely cooled.
Since the housing of the calibrator is made of metal, only power cables with ground wire may be used.
Operate the calibrator exclusively with the power cable provided. The power cable connector is on the
bottom of the calibrator, i.e. when using a different type of cable, the calibrator may topple over.
If the calibrator is not used for an extended period of time, humidity may penetrate into the heating
element due to the material used (magnesium oxide).
After transporting or storing the calibrator in a humid environment, the heating elements must thus be
heated slowly when starting the calibrator. During the drying process the calibrator will not have attained
the isolation voltage required for protection class I (refer to chapter 5).
The noise levels of all block calibrators of the TP 38… / TP 38… E series are below 70 dbA.
2.4 Ground wire monitoring (TP 38 650 and TP 38 650 E)
For checking the basic isolation of the heater, the calibrator is equipped with a ground wire monitor. The
monitoring unit operates independently of the other controller components and switches off the power supply
of the heater as soon as the calibrator loses the connection to the ground wire system of the isolation. This
condition can only be noticed by the fact that the calibrator will be cooled to room temperature. Once the
connection to the ground wire system has been re-established, the monitoring unit automatically reconnects
the heating circuit to the power system (refer to chapter "Troubleshooting").
