GENERAL OPERA

TIONS

5. GENERAL OPERATIONS

5.1. STARTING UP THE MONITOR

Detailed below is a general outline of the steps required to perform accurate measurements.

1. Mount the 

Monitor

 on a stable support wall. 

2. Connect the 

HI1285‑8 

or

 HI1285‑9

 probe to the 

Monitor

. 

3. Connect the power adapter to the 

Monitor

 and switch it on.

4. Set up the 

Monitor

. See the “Monitor MENU” section for details.

5. Calibrate the probe.

Mounting the Monitor 

The 

HI981420

 is supplied with mounting holes in the enclosure. Utilizing all the mounting holes, 

it should be wall mounted at eye‑level, on a vibration‑free surface. When choosing installation 
location consider power source, tank location (with regard to length of sensor cable) and operating 
temperature (50 °C/122 °F maximum).
