OPERATIONAL GUIDE Each meter is supplied with batteries. Remove the battery cap, unwrap the supplied batteries and install them while paying attention to their polarity (see also the "Battery replacement" section for more details). TAKING MEASUREMENTS Connect a suitable temperature probe to the meter (see pages 12-14 for a complete list of Hanna probes). Note: HI 935007 has a fixed probe. To switch the meter ON, press the ON/OFF button on the front of the meter.
CALIBRATION CHECK All the models are provided with automatic Cal-Check feature at start-up, which allows the user to check the instrument calibration status. If the meter is calibrated, the display will stabilize and show “0.0 °C” (±0.3 °C) in a few seconds. Contact your dealer or your nearest Hanna Service Center for recalibration, if necessary. HOLD FEATURE (HI 93501S, HI 93503) The hold function is activated by pressing the HOLD key.
WARNING MESSAGES NO PROBE message If the probe is not connected “NO PROBE” message is displayed. DAMAGED PROBE message When the readings are very far from the reading range, the probe can be damaged, “DAMAGED PROBE” message is displayed.
BATTERY REPLACEMENT When the remaining battery life is less than 10% the battery tag blinks on the display to warn the user. If the battery level is low enough to cause erroneous readings, the Battery Error Prevention System (BEPS) turns the meter off. Immediately replace the batteries with new ones. Battery replacement must only take place in a non-hazardous area. The batteries are accessed by opening the battery compartment cap on the bottom of the instrument. Replace the three 1.
TEMPERATURE PROBES Hanna offers a wide range of probes to meet your needs with air, liquid, penetration and surface measurements. All Hanna temperature probes are pre-calibrated at the factory and ready-to-use. These interchangeable probes make it possible to switch from one probe to another without requiring recalibration. Hanna probes are also available in different handle colors to avoid cross contamination during testing. Note: To clean the meters, do not use aggressive detergents.
