Then press YES to confirm the value, or NO to reenter the value. Press CAL/MEAS to exit Set Temp mode. NOTE: This key is active only in the Measurement mode.
- Page 8 MR/OPTIONS Primary function: Recall stored values, in last-in-first-out sequence. The meter displays recalled values according to the current mode. If there are no stored values in memory, the ERR annunciator appears. To recall all stored values, press MR repeatedly. To exit from MR mode, press CAL/MEAS. In the MR mode, you can also select PRINT to send recalled values to the RS-232 output.

Page 11: Ph Calibration
4. pH calibration This instrument stores up to 5 calibration points to ensure accuracy. You can perform 5-point calibration in any order with standard pH buffers: 1.68, 4.01, 7.00, 10.01, and 12.45. This meter features auto buffer recognition at these 5 values for faster calibration. Or, you can enter your own custom pH buffer introduction values (see step 5 below for instructions). -
