4. The [] DOWN key. 4a. During Calibration/Setting mode this key will decrement the blinking digit of the active parameter. 4b. During” DO CALIBRATION” the user can press this key to skip ZERO calibration. 5. The [] ENTER key. During Calibration/Setting mode, this key will save the current modified parameter and move to the next parameter on the page if the parameter is the last one in the page then it will move to first parameter on the next available page. -

4. STD. CAL or PROD. CAL: In this calibration you can choose first if you are doing a “STD. CAL” (Standard Calibration) or a “PROD. CAL” (Product Calibration). To accurately calibrate the model 6312DTB/DTF you will need the following information: i. The approximate pressure (in mBar) of the region in which you plan to take your dissolved oxygen measurements. - Page 13 (a). STD.CAL – The unit of this calibration will depend on the unit of DO at normal/main mode. Follow these steps to do a Standard Calibration: 1. If the DO probe is new and not yet connected to the meter, follow the DO probe manufacturer’s instruction on how to prepare the probe for first use and how to connect to the meter.

(See chapter V. CONTROLLING THE RELAYS ). User can use [] and [] keys to select the relay1 action and press [] key to save the setting. After you select the RELAY1 action you can now select the RELAY1 set point. Use [] and [] keys to change the blinking digit, use the [MODE/-] key to select another digit and the [] key to save the new set point value. -

4. RS 485 ID – this is the unique ID/Address for the unit. If you are connecting multiple model 6312DTB/DTF or other Jenco models for logging purposes then this ID/Address must be unique for each connected unit. This ID/Address is the same address that must be used by the PC program to communicate with this unit. -
Page 17: Relay Output Load
B. RELAY OUTPUT LOAD The current through the relay output contacts should not exceed 5 Amp at 115 VAC and 2.5 Amp at 230 VAC in order not to cause permanent damage to the relay contacts. This rating is specified for resistive loads only. C. -
Page 18: Temperature Relay
E. TEMPERATURE RELAY One relay channel is available for temperature display which has independent set point, action (see Figure. 1) setting (HIGH or LOW) and hysteresis value. The action of the Temperature relay is dependent on set point, relay action (HIGH or LOW), hysteresis value and the current Temperature display. -
