Then press the

key. This will bring up the PASSWORD screen. To prevent
unauthorized access to calibration data, a password must be entered to access any calibr

typically 270. Units with a –HV or –EHV output range option may have a dif
range value and corresponding calibration password. Check the s
screen when in doubt.
The password can be entered using the knob to dial in the number. The password can also
