How To Recalibrate The Humidity Display on Raching MON Series Electric Humidors

Every now and then we’ve had a customer tell us that their Raching display screen is reading something different then their internal hygrometers. Usually the display screen is reading higher than the actual humidity inside of the cabinet. Your humidor is not broken, your screen just needs a quick recalibration.

So on this page we’re going to help walk you through how to do a quick display screen recalibration on your Raching electric humidor.

When Should You Recalibrate?

A screen recalibration or adjustment might be needed if

• The display reading doesn’t match a calibrated hygrometer
• You notice a consistent difference of 2-5% RH
• You’ve moved the humidor to a different environment

 

Before You Start

For best results:

• Place a calibrated hygrometer inside the humidor.
• Allow 24-48 hours for readings to stabilize.
• Compare the Raching display reading to the calibrated hygrometer.

Example:

• Raching Display = 71% RH
• Calibrated Hygrometer = 68% RH
• Difference = -4%

You will need to adjust the Raching display by -4%. We will use this example for the rest of the recalibration exercise.

Warning Notes: It is advised by Raching to not adjust humidity more than 4% at a time. If there is a humidity discrepancy of more than 4% points- let’s say 6%. You will need to adjust 4%, wait 48 hours, and then adjust the remaining  2% after the 48 hour adjustment period. 

 

Step 1: Enter Calibration Mode 

Press and hold the minus key for 6 seconds until ON appears and then release it. If OF appears, press the minus key repeatedly for 6 seconds until ON appears.

 

Step 2: Enter The “A” Function Parameters

• Long press the setting button until the parameter A01 appears
• Then press the settings sign once to select parameters A02, A03, A04 until A08 appears
• Then press the plus/minus button to change the number to the reflect the humidity difference. For this example its -4.
• You will change the A functions for the following parameters:
  • A08, change to -4
    
  • A10, change to -4
    
  • A12, change to -4
    
  • A14, change to -4
    
  • A16, change to -4
    

Warning Notes: DON'T CHANGE A01 FOR ANY REASON. 

 

Step 3: Wait 48 hours 

You will need to wait 48 hours for the cabinet to readjust. Recheck display and internal hygrometers after 48 hours.

Important Notes

• Calibration only adjusts the displayed humidity reading.
• It does not change the actual humidity inside the humidor.
• Always use a calibrated hygrometer as your reference.
• Allow 48 hours after any major humidity adjustments before recalibrating.

Common Questions

My display is off by 1%

A: This is normal and within acceptable tolerance. Raching has an advertised +/- 1% RH

My display is off by more than 5%

Verify before calibration:

• Water reservoir is filled
• Door seal is closing properly
• Reference hygrometer is calibrated
• Cabinet is in a indoor controlled environment

How Often Should I Recalibrate?

Most users never need to recalibrate. Only recalibrate if you notice a consistent difference between the display and a trusted hygrometer.

Where can I find a hygrometer for the inside of my cabinet?

We have two great digital hygrometer choices: 

1. Xikar PuroTemp Digital Hygrometer

2. Xikar PuroTemp Wireless & Digital Hygrometer
