2.2 Mounting or Replacing the Batteries 2.2 Mounting or Replacing the Batteries • Do not mix old and new batteries, or differ- ent types of batteries. Also, be careful to observe battery polarity during installation. Otherwise, poor performance or damage from battery leakage could result.
Page 23
2.2 Mounting or Replacing the Batteries New batteries should last for about 15 days of con- tinuous use, with the auto power save function switched off. Batteries should last for about 1 month or more of continuous recording using the product in interval recording mode (with the recording interval set to 1 minute or longer), and with the auto power save function switched on.
2.3 Connecting the Temperature Probe 2.3 Connecting the Temperature Probe • To avoid damage to the product, protect it from vibration or shock during transport and handling, and be especially careful to avoid dropping. • To avoid damaging the product, never connect any sensor other than the 9478 or 9479 SHEATH TYPE TEMPERATURE PROBE (with recording switch) to the sensor connector.
Page 25
2.3 Connecting the Temperature Probe • The sensor used in the temperature probe is a precision platinum element. Please note that excessive voltage pulses or static discharges can destroy the element.To avoid damage or malfunction, avoid hitting the tip of the tempera- ture probe and overly bending the leads.
